The regular action in the Rock-Paper-Scissors is to play the 'Rock-paper-scissors' -game (or 'Stone-paper-scissors' -game). The result of a round of 'Rock-paper-scissors' is displayed in console after the user settable amount of delay (defined in milliseconds with the parameter -Delay, which has the aliases called -Wait and -Pause).

To play a round of the Chinese game called 手勢令 (Shoushiling), a parameter -Chinese may be used in the command. To play a round of the Japanese game called 虫拳 (Mushi-ken), a parameter -Japanese may be used in the command. To play the ancient Roman game 'Micare Digitis', a parameter -Roman may be used in the command. To read more about the origins of each game, please see the History section.

To see the the rules of a game, a parameter -Help (which has the aliases of -Text and -Definition and -Rules) may be added to each and every command. The definitions of each game are decribed in the Description section below. To hear the result in code language, an -Audio parameter may be added to the command.

• Parameter -Chinese

  To play a round of the Chinese game called 手勢令 (Shoushiling), a parameter -Chinese may be used in the command.

• Parameter -Japanese

  To play a round of the Japanese game called 虫拳 (Mushi-ken), a parameter -Japanese may be used in the command.

• Parameter -Roman

  To play the ancient Roman game 'Micare Digitis', a parameter -Roman may be used in the command.

• Parameter -Delay

  The result of a 'Rock-Paper-Scissors' -game is displayed in console after the user settable amount of delay (defined in milliseconds with the parameter -Delay, which has the aliases called -Wait and -Pause). The value should be an integer between 0 and ten billion. All values under 1000 (one second) are shown without a progress bar, and for instance, a value of 750 results in a slower pace without any progress bars and a value of 178 is a reasonable responsive UX without any progress bars. The default value is 3030, which shows the result after roughly three seconds and displays a progress bar to count down the time and equals to three pre-steps (primes) i.e. 3-2-1-signal. To get the result instantly, please set the value of parameter -Delay to number zero (-Delay 0). To get the result after two pre-steps (primes) i.e. 2-1-signal, please set the value of -Delay parameter between 2000 and 2499 (where the value above 2000 is defining, how long should it take, before the countdown from two commences). The threshold level for the delay, above which additional instructions to cancel the countdown are displayed is defined on line 27 with the $delay_notify_threshold variable (in milliseconds). The usage of fractions of milliseconds with the -Delay parameter is not supported.

• Parameter -Help

  To see the the rules of a game, a parameter -Help (which has the aliases of -Text and -Definition and -Rules) may be added to each and every command.

• Parameter -Audio

  If the -Audio parameter is used in the command, after the results have been displayed a morse code character e (one beep) or a morse code character s (three beeps) or a morse code character 5 (five beeps) is emitted through the speakers and in the case of 'Micare Digitis', the number of beeps equals the number of fingers the opponent is showing. The default audio mode in Rock-Paper-Scissors is "silent". To find out, which sound is emitted when, please see the table below.

  -Audio Outputs of 'Rock-paper-scissors' and 手勢令 (Shoushiling) and 虫拳 (Mushi-ken)

  Morse Code Character e	Morse Code Character s	Morse Code Character 5

• Generates an output of a selected game in console. Displays a progress bar, if -Delay is set over 1000 (one second). Emits a sound, if -Audio parameter is used.

• Please note that each of the parameters can be "tab completed" before typing them fully (by pressing the [tab] key, not including the aliases)).

• Please note that only one game type at a time (-Chinese, -Japanese, -Roman or 'Rock-paper-scissors') may be selected to play in one round due to the radically different nature of the games.
• Please see the Description section below for definitions of each game.

  Description:

  (1) 手勢令 (Shoushiling)

  In 手勢令 (Shoushiling or 'shǒushìlìng', literally: 'hand command') each participant shows one of the three hand signals after a synchronized countdown, which consists of one to three pre-steps (i.e. 1-signal to 3-2-1-signal), has elapsed. It is essential for the flow of the game for all participants (1) to know the number of pre-steps, for them to be certain, on which count the signal shall be released and (2) then to be in the same rhythm before the handsigns are signalled. If at any time the players are not in synch with their pre-steps (primes), it is recommended to restart the game, since having players deliver their throw at the same time is critical in ensuring a fair match. For fairness of the play, it is recommended to agree on the number of rounds to be played before the playing begins, so that each participant will know whether the outcome will be decided in one go or whether the game is in a tournament mode (best out of [uneven_number_of_rounds]). The released hand signs each have an inherent value in which one sign will always be better than the released hand sign and another hand sign will be worse than the released hand sign – furthermore it is ordained that all the signs together are valued successively so that they form an 'Infinite Loop of Betterness'. In 手勢令 (Shoushiling) this loop is formed by valuing the hand signals as follows: 蜈蚣 Centipede (wu) wins against 蛇 Snake (she) 蜈蚣 Centipede (wu) loses against 蛙 Frog (wa) 蛇 Snake (she) wins against 蛙 Frog (wa) 蛇 Snake (she) loses against 蜈蚣 Centipede (wu) 蛙 Frog (wa) wins against 蜈蚣 Centipede (wu) 蛙 Frog (wa) loses against 蛇 Snake (she) Classic 手勢令 (Shoushiling) – Chinese 蜈蚣 CENTIPEDE (wu) 蛇 SNAKE (she) 蛙 FROG (wa) 蜈蚣 CENTIPEDE (wu) Tie 蜈蚣 Centipede (wu) 蛙 Frog (wa) 蛇 SNAKE (she) 蜈蚣 Centipede (wu) Tie 蛇 Snake (she) 蛙 FROG (wa) 蛙 Frog (wa) 蛇 Snake (she) Tie In 手勢令 (Shoushiling) ties, where the participants show the same hand signal as a result, per se, cannot be broken, but the occured 'Tie-Break Situation' is usually resolved by playing another round of 手勢令 (Shoushiling) immediately after the existence of 'Tie-Break Situation' has been confirmed.

  In 手勢令 (Shoushiling) the signal code language differs from its Western counterparts, and in 手勢令 (Shoushiling) it is customary to use the little (pinky) finger when signalling the 蜈蚣 Centipede (wu), the index finger when signalling the 蛇 Snake (she) and the thumb when signalling the 蛙 Frog (wa).

  (2) 虫拳 (Mushi-ken)

  In 虫拳 (Mushi-ken) (ken (literally 'fist', 'grip', 'force' or 'strike') (拳) of the small animals, one of the games of 三竦み拳 ('sansukumi-ken', ken (literally 'fist', 'grip', 'force' or 'strike') (拳) of the three who are afraid of one another)) each participant shows one of the three hand signals after a synchronized countdown, which consists of one to three pre-steps (i.e. 1-signal to 3-2-1-signal), has elapsed. It is essential for the flow of the game for all participants (1) to know the number of pre-steps, for them to be certain, on which count the signal shall be released and (2) then to be in the same rhythm before the handsigns are signalled. If at any time the players are not in synch with their pre-steps (primes), it is recommended to restart the game, since having players deliver their throw at the same time is critical in ensuring a fair match. For fairness of the play, it is recommended to agree on the number of rounds to be played before the playing begins, so that each participant will know whether the outcome will be decided in one go or whether the game is in a tournament mode (best out of [uneven_number_of_rounds]). The released hand signs each have an inherent value in which one sign will always be better than the released hand sign and another hand sign will be worse than the released hand sign – furthermore it is ordained that all the signs together are valued successively so that they form an 'Infinite Loop of Betterness'. In 虫拳 (Mushi-ken) this loop is formed by valuing the hand signals as follows: なめくじ (蛞蝓) Slug (namekuji) wins against へび (蛇) Snake (hebi) なめくじ (蛞蝓) Slug (namekuji) loses against かわず (蛙) Frog (kawazu) へび (蛇) Snake (hebi) wins against かわず (蛙) Frog (kawazu) へび (蛇) Snake (hebi) loses against なめくじ (蛞蝓) Slug (namekuji) かわず (蛙) Frog (kawazu) wins against なめくじ (蛞蝓) Slug (namekuji) かわず (蛙) Frog (kawazu) loses against へび (蛇) Snake (hebi) Classic 虫拳 (Mushi-ken) – Japanese なめくじ (蛞蝓) SLUG (namekuji) へび (蛇) SNAKE (hebi) かわず (蛙) FROG (kawazu) なめくじ (蛞蝓) SLUG (namekuji) Tie なめくじ (蛞蝓) Slug (namekuji) かわず (蛙) Frog (kawazu) へび (蛇) SNAKE (hebi) なめくじ (蛞蝓) Slug (namekuji) Tie へび (蛇) Snake (hebi) かわず (蛙) FROG (kawazu) かわず (蛙) Frog (kawazu)) へび (蛇) Snake (hebi) Tie In 虫拳 (Mushi-ken) ties, where the participants show the same hand signal as a result, per se, cannot be broken, but the occured 'Tie-Break Situation' is usually resolved by playing another round of 虫拳 (Mushi-ken) immediately after the existence of 'Tie-Break Situation' has been confirmed.

  In 虫拳 (Mushi-ken) the signal code language differs from its Western counterparts, and in 虫拳 (Mushi-ken) it is customary to use the little (pinky) finger when signalling the なめくじ (蛞蝓) Slug (namekuji), the index finger when signalling the へび (蛇) Snake (hebi) and the thumb when signalling the かわず (蛙) Frog (kawazu (modern: かえる kaeru)). Movements are performed very quickly, and the game is usually played until three or five wins. The game is customarily played only with right hand while the left hand was used to count the wins. The participants could also follow the alternated ritus of Janken Style, where both participants start by saying 'Saisho (wa) guu' (Starting with a rock), and after holding out a closed fist raise their primary hand slightly, and follow it with 'janken pon!' simultaneously throwing out their move, whether it's a slug, snake or frog. If there's a tie (a draw or 'aiko', if both participants chose the same move), they say 'Aiko desho!' (It seems like a tie!) and repeat the ritual 'Saisho guu, janken pon' in an almost trance-like rapid-fire succession until one player (finally) wins.

  (3) Micare Digitis

  In 'Micare Digitis' (Flashing of Fingers) each participant shows zero to five fingers after a synchronized countdown, which consists of one to three pre-steps (i.e. 1-signal to 3-2-1-signal), has elapsed. It is essential for the flow of the game for all participants (1) to know the number of pre-steps, for them to be certain, on which count the finger(s) shall be shown and (2) then to be in the same rhythm before the handsign is signalled. If at any time the players are not in synch with their pre-steps (primes), it is recommended to restart the game, since having players deliver their throw at the same time is critical in ensuring a fair match. For fairness of the play, it is recommended to agree before the playing begins on the number of rounds a participant must guess correctly (or points achieve) in order to win the match ('Micare Digitis' is usually played in a tournament-mode). In 'Micare Digitis' at the same time when a hand sign is signalled also a number, which should represent the participants guess of the total number of fingers shown on the current round, is pronounced (usually a number ranging from zero to ten is uttered). This guess is validated correct or false by the total number of fingers that can be seen. In 'Micare Digitis' ties (draws), where the participants pronounce the same number as a result that is validated as correct, per se, cannot be broken, but the occured 'Tie-Break Situation' is usually resolved by playing another round of 'Micare Digitis' immediately after the existence of 'Tie-Break Situation' has been confirmed. After each round, however, the fingers are counted to see, if anyone guessed the total number of fingers correctly. If one of the participants guessed correctly, that person wins the round, and one point is awarded to that (lucky) player. If no one guessed the right number then nobody wins that round, and no points are awarded for that round. If all participants guessed the correct answer, then it is a draw ('Tie-Break Situation') and nobody gets credit for winning the round, and no points are awarded for that round. The play continues until one of the participants reaches the number of rounds won (or points) needed to win the match.

  In 'Micare Digitis' the hand-signs are signalled with a primary hand (by extending the fingers, if any), while the secondary hand is kept out of sight, usually behind one's back. The secondary hand is usually used to count the current personal score (i.e. the number of rounds won). In 'Micare Digitis', when signalling the number three, it might be customary to use a similar hand sign to what is seen some of the NBA referees using while indicating a three-point-shot-attempt, where index finger is curved beside the thumb while the last three digits remain straight. When signalling the 'Zero' or 'no fingers' in 'Micare Digitis', the extended hand is accompanied with a closed fist in a similar fashion to the 'Rock' in 'Rock-paper-scissors'.

  (4) 'Rock-paper-scissors' -game

  In 'Rock-paper-scissors' (or 'Stone-paper-scissors') each participant shows one of the three hand signals after a synchronized countdown, which consists of two or three pre-steps (i.e. 3-2-1-signal or 2-1-signal), has elapsed. It is essential for the flow of the game for all participants (1) to know the number of pre-steps, for them to be certain, will the signal be released on third or fourth count and (2) then to be in the same rhythm before the handsigns are signalled. If at any time the players are not in synch with their pre-steps (primes), it is recommended to restart the game, since having players deliver their throw at the same time is critical in ensuring a fair match. For fairness of the play, it is recommended to agree on the number of rounds to be played before the playing begins, so that each participant will know whether the outcome will be decided in one go or whether the game is in a tournament mode (best out of [uneven_number_of_rounds]). The released hand signs each have an inherent value in which one sign will always be better than the released hand sign and another hand sign will be worse than the released hand sign – furthermore it is ordained that all the signs together are valued successively so that they form an 'Infinite Loop of Betterness'. In 'Rock-paper-scissors' this loop is formed by valuing the hand signals as follows: Rock wins against Scissors Rock loses against Paper Scissors wins against Paper Scissors loses against Rock Paper wins against Rock Paper loses against Scissors Classic 'Rock-paper-scissors' ROCK PAPER SCISSORS ROCK Tie Paper Rock PAPER Paper Tie Scissors SCISSORS Rock Scissors Tie In 'Rock-paper-scissors' ties, where the participants show the same hand signal as a result, per se, cannot be broken, but the occured 'Tie-Break Situation' is usually resolved by playing another round of 'Rock-paper-scissors' immediately after the existence of 'Tie-Break Situation' has been confirmed.

  In 'Rock-paper-scissors' it is customary to use the closed fist when signalling the 'Rock' (where the wrist is positioned similarly as to holding a glass full of water (and the fingers are closed together) with the thumb resting about at the same height as the topmost finger of the hand. The thumb is usually not concealed by the fingers), the open horizontal flat hand palm facing down when signalling the 'Paper' (which is delivered in the same manner as rock with the exception that all fingers including the thumb are fully extended and horizontal with the points of the fingers facing the opposing player) and a fist with the index and middle fingers forming a vertical V when signalling the 'Scissors' (which is delivered in the same manner as rock with the exception that the index and middle fingers are fully extended toward the opposing player. It is considered good form to angle the topmost finger upwards and the lower finger downwards in order to create a roughly 30-45 degree angle between the two digits and thus mimic a pair of scissors).
