Countdrop
Daily number chain puzzle
Only for iPhone
Free · In‑App Purchases
iPhone
Drop a tile. Match the count. Watch it cascade.
Countdrop is a number puzzle with one rule: a tile clears when its number matches the length of the continuous horizontal or vertical run it belongs to, including itself. Each drop can reshape the board and set off a chain of clears.
THE CHAIN IS THE POINT
Clearing tiles cracks the gray blocks beside them, revealing new numbers that may clear in turn. Plan ahead, line up your drop, and turn one move into a satisfying cascade.
FOUR WAYS TO PLAY
- Campaign: work through 999 puzzle levels.
- Daily Challenge: everyone gets the same tiles, in the same order, with one attempt each UTC day. Build your streak and share your result.
- Endless: keep the board under control as new rows rise.
- Zen: settle into a more relaxed way to play.
MORE THAN COLOR
Discover 26 themes, from glowing and frosted tiles to playful plush bears, dramatic fireballs, underwater light, storms, and blooming gardens. Unlock themes through play, with additional cosmetic themes available as optional purchases.
