Current season
Loading the current pool…
The community’s most-voted charity receives half the pool.
The other half rewards the top five eligible players by MMR.
Paid patches grow the pool. After card-processing fees, each payment is divided:
80% to the prize poolShared between charity and players
20% to itgetsit llcThe company that powers PatchDuel
The company’s share supports hosting, AI development and running the game. It is separate from the pool shown above.
Play ranked games through Find Match. Finish in the top five by MMR when the season ends to earn a cash prize. Entry is free; buying a patch is never required.
Shares are percentages of the players’ half. Amounts grow with the pool; cent rounding goes to charity. Unfilled places and prizes unclaimed after 60 days also go to charity.
More than first place
The #1 player can choose up to 5 of the 10 highest-rated eligible player patches to become permanent and carry into the next season.
All other seasonal patches are removed, and rankings reset. The next season starts from the base game, including patches already made permanent.
Awards are subject to eligibility and fair-play review. Winners claim through the Hall of Fame. Read the Terms & prize rules ↗
