Pillchain is the kind of game you open “for a minute” and suddenly you’re still playing because everything feels so good. A bucket of glossy, candy-bright balls bounces and settles with satisfying physics, and with one touch you lock onto a color—the bucket lights up to match it, the world seems to lean in, and you start drawing a glowing chain through every ball you can reach. Keep connecting the same color to build an unstoppable link, watch your score explode, and feel the rush as a continuous tone climbs in pitch with every perfect addition. It’s smooth, punchy, and ridiculously rewarding when a huge chain snaps into a clean, sparkling clear. But it doesn’t stay easy. New balls rain down, the bucket gets tighter, and the game evolves as you survive: balls gradually shrink (down to a minimum you can still comfortably tap), then the challenge ramps by adding more colors and pressure. Every run becomes a battle of control—clear space, chase bigger chains, and don’t let the bucket overflow. When you finally get pushed over the edge, you’ll get a full breakdown of your run: your score, how long you lasted, your best chain, and which colors you crushed the most. Want to set the mood? Choose your music vibe (EDM, ambient, chill and more), fade smoothly between tracks, and fine-tune SFX and music volume exactly how you like. Play with ads at the bottom during gameplay, or grab the one-time “Remove Ads” in-app purchase and keep the bucket blissfully clean.

Rules Change is a minimalist puzzle game where the rules never stay the same. Each round presents a simple rule and a set of shapes. Follow the rule correctly to continue — but be careful. With every new round, the rule changes, reverses, or contradicts what you just learned. The challenge isn’t speed alone, but adapting your thinking as expectations shift. There’s no memorization, no patterns to rely on, and no tricks you can use forever. The only way to score higher is to stay flexible and react under pressure. Features: • A new rule every round • Simple, abstract visuals with no distractions • Increasing difficulty as rules change faster • A countdown timer that rewards quick thinking • Score based on how long you can adapt Rules Change is designed to test mental flexibility, focus, and decision-making. It’s easy to start, difficult to master, and challenging in a way that stays fair. How long can you keep up when the rules won’t stay the same?
