Rock Paper Scissors Variants - Mukjjippa, RPS Lizard Spock, and More

Rock Paper Scissors is not just one game. Korea has Mukjjippa, Odd-Even, and Hana-Bbaegi; the English-speaking world has the famous 5-option Rock Paper Scissors Lizard Spock from The Big Bang Theory. Here is the Gababo guide to RPS variants.

Mukjjippa — Rules and How to Win (Korean traditional variant)

Mukjjippa starts with a normal RPS round to decide who attacks. The attacker calls "Muk!" (rock), "Jji!" (scissors), or "Ppa!" (paper) while throwing a shape, and the defender throws at the same time. If both show the same shape, the attacker wins and the game ends. If the shapes differ, the two throws are compared as a normal RPS round — the winner takes the attack role and play continues. How to win: as the attacker, repeating the shape you just threw is the basic pressure play, because defenders tend to switch shapes in reaction to the previous exchange. As the defender, decide your next shapes in advance so the attacker's call doesn't pull you along. A psychological extension that turns short RPS into a longer mind game.

Odd-Even RPS

Both players show 1-5 fingers simultaneously. One side calls Odd, the other Even, and the total determines the winner. No draws — 50/50 odds, great for quick decisions.

Hana-Bbaegi (One-hand Pull)

Two-handed RPS variant. Both players throw two shapes simultaneously, see the opponent's two hands, then "pull" one hand to use for the duel. Reads the opponent's pull pattern — much deeper than basic RPS.

Rock Paper Scissors Lizard Spock

Five-option RPS popularized by The Big Bang Theory. • Scissors cut Paper, decapitate Lizard • Paper covers Rock, disproves Spock • Rock crushes Scissors, crushes Lizard • Lizard eats Paper, poisons Spock • Spock vaporizes Rock, smashes Scissors Draw probability drops to 1/5, making single-throw matches more decisive.

Practical Uses of RPS Variants

RPS variants are used for more than just gaming: • Drinking games — penalty selection • Dining out — who pays • School/work — chore order, presentation order • Quick decisions — who drives in a carpool • Tournaments — seeding and bracket order Gababo's friend invite mode lets you settle these decisions remotely.
