Three in a
row. One number
higher.

Place tiles, connect matching numbers, and trigger chain reactions. Caskado rewards planning — and punishes dead ends.

Learn it in four moves

Easy to learn,
hard to master.

No manual required. But once you can see the cascade before you place the tile, the game opens up.

Use impulse

After 7 moves without a merge, the impulse tile appears and copies the most common value among its 4 orthogonal neighbors (up, down, left, right).

The core idea

The cascade makes
all the difference.

One move can trigger a chain reaction that reshapes the board and multiplies your score. Smart players wait for the right moment.

Cascade multiplier

Every merge in a chain reaction raises the multiplier. Plan two steps ahead — the bonus scales fast.

Impulse tile ✦

After 7 moves without a merge, an impulse tile appears. It copies the most common value among its 4 orthogonal neighbors (up, down, left, right) — saving almost any stuck position.

What's inside

More than just
a few numbers.

Chain reactions with a bonus

Every follow-up merge multiplies your score. A planned three-step chain can beat more than 20 clean single moves — the skill gap is measurable.

Impulse tile for stuck boards

After seven moves without a merge, the impulse tile steps in. It copies the most common value among its orthogonal neighbors and gets the board moving again.
