Coilbloom

About

Connect the pipes. Close the loop. Cool the reactor. Coilbloom is a colorful circuit-building puzzle with a strategic twist: placing tiles adds heat, while completing loops clears space and cools the board. Take your time to plan. The pressure comes from your moves, not a countdown. FIND YOUR NEXT LOOP Choose a hex tile, rotate its pipes, and connect matching colors. Close a circuit to earn energy and vent heat. Keep enough space for your next idea before the reactor overheats or the board fills up. CHOOSE HOW YOU PLAY Clear stages and choose temporary modules for that run. Make small loops more rewarding, improve cooling, or give yourself more room to recover. Spend the Research Shards you earn on permanent upgrades in the lab. MASTER FIVE REACTORS Start with one color, then take on new colors, tighter spaces, and special hexes. Each reactor has three mastery stamps to earn. Finish the campaign to unlock RUNAWAY, an endless mode with an escalating challenge and a personal record to beat.
