Mindboo isn't here to relax you. It's here to ignite you. This is a mental survival game. Every run throws your brain into a new high-pressure arena — and your only job is to survive without breaking. HOW IT WORKS You tap, count, react, and make split-second decisions — while the arena spins, the screen flips, the timer collapses, and the rules change mid-round. Simple to grasp in one round. Brutal to master. THE ARENA FIGHTS BACK The chaos doesn't come from complexity — it comes from pressure. Adapt instantly, or fold. Some arenas give you one mistake. Some give you none. EARN YOUR IDENTITY You don't get a score. You get a tag — proof of how your mind held under fire: - Chaos Born - Untouchable - Lightning - Last Brain - Fastest Alive FACE YOUR RIVALS Go head-to-head with real players, AI clones that mimic how they actually performed, and shadow versions of your own past runs. The arena never sleeps. BUILT FOR THE WAY YOU PLAY Short, intense sessions. Instant retry. Play on a break and still walk away feeling like you survived something. Not brain training. Not a puzzle. An arena. Survive the chaos. Prove your mind doesn't break.

Launch polygons, merge them, and relax with Polymerger, the most satisfying shape-merge puzzle game. Toss shapes onto the board, merge polygons into larger ones, and see how far you can go! There’s no limit to the number of sides you can achieve—so keep merging and aim for the highest score! But be careful – don't let the polygons stack up too high! If a polygon touches the line for too long, you'll lose. Your game progress will be saved, so feel free to take a break and come back when you're ready to finish! NOTE: The saved game might become useless when updating/reinstalling the game. Make sure to finish your game before updating.

Verdict
The clearest difference is in-app purchases: Polymerger at none against Mindboo's 7. Polymerger also leads on ads (none vs shown) and rating (5.0 vs 4.7). Mindboo's advantage is update cadence (monthly vs every 3 months) and ratings volume (127 vs 9). On price and device support there is nothing between them.
