About This Demo

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.

SUMOO Demo offers:

• 20 levels, from every other chapter of the full game

• A first taste of every core mechanic; stones, pits, portals, and multipliers

• The same simple rule, the same growing depth, just a shorter run

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

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.
