About

ThermoMerge

Read full description

ThermoMerge is a block puzzle game built around one simple idea: balance. You’ll slide red (hot) and blue (cold) blocks across a 5x5 grid to merge tiles and build higher values. But when a hot block meets a cold one of the same value, they cancel each other out — clearing space and giving you points. Every move adds a new block, so each decision matters. The goal is to keep the board from filling up for as long as you can. Features: 1. Merge hot with hot, cold with cold, or cancel them out by combining both of the same value 2. Slide one block at a time with simple swipe controls 3. Clean visuals and smooth animations 4. No timers or distractions — just thoughtful puzzle solving 5. Easy to pick up, hard to put down
