Need help with Sort & Stack? Most questions are answered below. If not, reach out — we read every email.
Drag a piece from the top queue into any tube. Stack 4 or more blocks of the same color in a row inside a tube — they pop automatically and you score points.
When a pop causes blocks above to fall and trigger another pop, that's a combo. Higher combos = bigger points, screen shake, and a colorful banner.
Reach the level's goal in fewer moves. The fewer the moves, the more stars. The 3-star threshold is shown on each level.
Every popped block gives 1 coin. You can also watch a free ad in the Store for +100 coins, complete daily logins for bonus coins, or buy coin packs.
• Undo — rewind your last move (100 coins)
• Hint — show the best placement (100 coins)
• Boost — tap any tube to empty it (100 coins)
If you don't have coins, tap the + badge on a power-up to watch an ad and use it free, or buy a coin pack.
Sign in to Game Center from Settings. Your highest single-level score, longest combo, and highest reached level are submitted automatically.
Yes. In the Store, tap Remove Ads ($4.99). One-time purchase, all interstitial and rewarded ads gone. The free "Watch Ad" button for bonus coins remains available if you want it.
Complete the previous level to unlock the next. Boss levels (every 25) are a bit harder — keep an eye out for the crown icon 👑.
