Boomstack: Cube Blast Merge

Match three to load the turret. Fire, pop the cubes, and keep going until the board is empty. Merge bullets into rainbow rounds that take out any color!

Boomstack is a match-3 puzzle with a blaster bolted on. Three genres in one loop: match-3, block blast and merge. Every match you make loads ammo. Every shot sends cubes tumbling under real gravity. Clear the board, move to the next level.

HOW TO PLAY

1. Tap three or more matching items on the board

2. Each match loads your turret with bullets

3. Fire at the cubes and watch gravity take them down

4. Merge bullets into rainbow rounds that clear any color

5. Empty the board to finish the level

WHAT MAKES IT DIFFERENT

🎯 A blaster inside a match-3: earn your ammo, then spend it well

🌈 Rainbow merges turn spare bullets into board-wide combos

🧊 Cubes fall with real weight, so no two clears look alike

🧩 Hundreds of levels built by hand, with new ones added often

👆 One thumb, one tap - that is the whole control scheme

🧠 Calm enough to unwind with, tricky enough to stay interesting

✈️ Works with no signal, on a plane or underground

🆓 Free to start

EASY TO START, TRICKY TO FINISH

The first boards teach themselves. Later ones do not: match carelessly and you run out of bullets with cubes still standing. Read the board, bank your rainbow merges, and spend every round where it counts.
