Foam Party is a light cartoon car wash game built for mobile play. Dirty cars arrive covered in mud, dust, leaves, bug marks, and oil stains. Pick the right tool for each mess, drag across the car, and watch the dirt blow away, wash down, soften with soap, or wipe clean with a sponge. City cars, sports cars, and trucks rotate through the levels, with more durable dirt appearing as you progress. Clear dirt quickly to build combos, earn star ratings from your finish time and best combo, and collect coins. Coins can trigger a foam bomb that soaps up every remaining mess at once. The game includes a first-run guide, sound toggle, local progress saving, and instant play without an account.

Everything begins with a single point. Tap the glowing core and watch simple shapes multiply into a hypnotic cosmic mandala. Points become lines, lines become triangles, and orbit after orbit your universe blooms into something beautiful. Polystar is a relaxing idle clicker made entirely of geometry. No clutter, no noise: just pure shapes, soft light and numbers that keep growing, even while you're away. TAP AND COMBO Tap the core to earn vertices. Keep tapping to build your combo and watch the whole mandala spin faster. BUILD YOUR UNIVERSE Unlock new shapes, each with its own orbit. As they fill up, they connect to each other and reveal new patterns. 47 UPGRADES Symmetries, fractals, sacred geometry... Every upgrade makes your universe more powerful and more beautiful. CATCH GOLDEN STARS Stars drift across your universe from time to time. Tap them for a big burst of vertices. TRIGGER THE BIG BANG When your universe reaches its limit, collapse it back into a single point. You'll earn Singularities that make you stronger forever, and start again, faster every time. Relax, tap, and let your universe grow.
