YOLO Games

YOLO Games is the hub of degen gaming. Play and earn across a range of provably fair, on-chain games.

We have developed 4 new games where players play against the liquidity pool.

1. Flipper - pick a side on a provably fair coin. If it lands on your predicted side, you win. If not, you lose.

2. Quantum - pick a number between 0.1 (1000x multiplier) and 95.00285 (1.0526x multiplier). Then select whether you want to 'hit' over or under it.

3. Laser Blast - you'll fire beams through an asteroid field to decimate the pesky invaders. Each one has a multiplier attached, representing the return you'll earn should you hit them. Adjust the number of rows of asteroids and risk level as you see fit!

4. Don't Fall In - Ever played Minesweeper? You're presented with panels arranged in a 5x5 grid, which you'll need to jump on. In doing so, you'll reveal what lies beneath: firm ground, or a pool of molten lava. If it's the latter, it's game over. The former? Congrats, you live to flip another panel --- or, you can quit while you're ahead, and cash out.
