About this game
Earn as many chips as possible before each deadline. Meet the quota, and advance to the next round. Fail? Play Russian roulette. And every time you fail, the chamber gets one bullet heavier.
Manipulate the coin. Collect and combine items that bend probability to your will.
Upgrade your coins, enhance items, and stack modifiers to control the odds. The deeper you go, the more you can break, but the deadlines get steeper, and the revolver cylinder spins closer.
Features:
Solo or Multiplayer roguelike. Play alone, compete or cooperate with other players.
Dynamic Probability System. Items, coins, and consumables stack to alter flip outcomes.
Russian Roulette. Miss a deadline and pray the chamber is empty to continue your run.
No Real Money, No Real Gambling. Every chip, every flip, every bullet is part of the game. PROBABILITY KING is designed to be broken and exploited, with your mind, not your wallet.
