About

8shape

Read full description

8shape is pool. But with shapes. Sink your shapes into the pockets, then the black 8shape – in the pocket opposite the one where you sank the last of your shapes. Sounds simple? Wait and see. YOUR SHAPES, YOUR GAME Circle, triangle, star or octagon: choose your cue shape and the shapes you play with. The more angular the shape, the trickier the game – and the more points. HOW YOU PLAY • Tap = shoot. The further from your cue shape you tap, the harder the shot. • The first shape you sink determines your suit. • Fewer turns, fast wins, trickshots: everything earns bonus points. • Several shapes in one shot? Combo bonus. • Fouls cost your multiplier. So: aim, don't hope. POWERUPS Win games, collect cards, level up your powerups and bring your favorites to the table: aim assist, explosion, freeze, earthquake and more – from common to legendary. MULTIPLAYER Challenge real opponents via Game Center – turn-based, with 48 hours per turn. Powerups included. Good luck, you'll need it. TRICKSHOTS Tricky challenge levels with star ratings. More art than a simple shot. NO ADS THAT INTERRUPT YOU No full-screen ad after a game, none on the way back to the menu, none mid-shot. Ads run only when you start one yourself – for a reward you actually want. ALSO • Leaderboards and 90+ achievements • Daily gift • Light and dark mode • Minimalist design, no clutter • Available in several languages, including English Shapes first. Then the 8. Can you do it in under 30 turns?
