The pool bar is always open! Ultrapool is a colorful roguelike about playing pool with a bunch of wacky balls with crazy effects. Carefully craft a perfect build and get the craziest trickshots! Get comfy, choose a cocktail, and get ready for a very special game of pool. Assemble a triangle of balls with strange effects and get the sickest trickshots. The bartenders won't be easy to impress! Ultrapool is an arcade-y colorful roguelike that plays like a pool version of Balatro and Super Auto Pets. Pocketing balls gives you score, and extra score gives you money you can spend at the bar to buy and improve your set of balls. Try to survive 10 rounds! We got both! Easy to pick up pool mechanics: just get the balls in the holes! But as you discover the wacky abilities the balls have, you'll get new ideas of how to get your score ever higher. A ghost ball that reappears on the table? A chicken ball that lays spherical eggs? A bomb that explodes if you bump it too much? The Earth? Anything is possible (as long as it's round and it rolls nicely, no cubes allowed!) Once you think you know the game, the cocktail bar opens. Ask the bartender to mix any two balls and he will serve you something special! Some of these will feel like they should break the game wide open, but you'll need every edge you can get if you want to pull off an all nighter.
