SUMOO is a minimalist grid-based puzzle game where numbers slide, meet, and add up. Push a tile and it slides until it hits a wall or another tile; when two tiles collide, their values combine. Guide the exact target value onto the goal tile to clear the stage.

As you play, new elements enter the mix: stones that block paths without combining, pits that swallow tiles that fall in, portals that teleport mid-slide, and multiplier tiles that double incoming values. Each mechanic is introduced step by step, one chapter at a time.

SUMOO offers:

• 100 levels across 10 distinct chapters

• A simple rule that keeps getting deeper

• Board elements: stones, pits, portals, and multipliers

• Unlimited undo, instant restart, and zero time pressure!
