Cascade!

Chain Reactions in Every Swipe

Cascade! is a sliding number puzzle where tiles merge into their sum. Swipe to slide all tiles — two equal tiles double (2 + 2 = 4), and two consecutive tiles combine (3 + 4 = 7, then 7 + 8 = 15). A single swipe can set off several merges at once. That's a cascade.

How to Play

• Swipe in any direction to slide all tiles simultaneously.
• Two tiles merge when their values are equal or consecutive — they differ by 0 or 1 (e.g. 2 & 2, 3 & 4, 7 & 8). The merged tile is their sum.
• Equal tiles double to build the even numbers; consecutive tiles cascade toward the target tile.
• A single swipe can trigger several merges along a row or column at once.
• A new tile spawns after each swipe that moves at least one tile.
• The game ends when the board is full and no matching or consecutive pairs remain adjacent.

Frequently Asked Questions

Which tiles merge?

Two tiles merge when their values are equal or consecutive — they differ by 0 or 1 — and the merged tile is their sum. So 2 and 2 make 4, and 3 and 4 make 7. Tiles that differ by 2 or more do not merge. This sum-based rule is what makes Cascade! different from 2048-style games.

How do I unlock new worlds in Campaign?

Each world (except the first) requires a minimum total star count from earlier worlds to unlock. Replay earlier levels to earn more stars if you're stuck.

How are stars awarded?

Each campaign level awards 1, 2, or 3 stars based on how efficiently you complete it — fewer moves earns more stars.

Does Cascade! work offline?

Yes. All game modes work fully offline. iCloud sync and Game Center leaderboards require a connection but are never required to play.

How do I reset my progress?

Open Settings from the main menu and tap Reset All Progress. You will be asked to confirm before anything is deleted.

My score didn't appear on the leaderboard — what happened?

Leaderboard scores require an active Game Center connection. If you were offline when you finished, the score will be submitted automatically the next time you open the app with a connection.
