Drop a card onto a tile that already holds the same digit. Instead of a new unit, the existing one ranks up — tier II, then tier III — hitting far harder from one tile. It costs a bit more than a fresh unit, and the preview shows the exact price.

You most likely dropped a card onto a tile that already had the same digit — that's a merge, which upgrades the unit rather than adding a new one. The in-game preview now shows the merge price before you release, so you'll always see it coming.

Open Settings → Remove Ads and complete the one-time purchase. Ads disappear immediately across the whole game.

Open Settings → Restore Purchases. Purchases are tied to your Apple ID, so they follow you to any device signed in with the same account. If it still doesn't restore, email us with your receipt.

Progress is stored on your device. Leaderboard rank (levels cleared) is tied to your Game Center account and follows your Apple ID. Local level progress does not currently sync between devices.

The difficulty ramps deliberately: early worlds teach, later worlds test. By the final world only a small fraction of players clear every level — that's by design. If a specific level feels broken (not just hard), please report it with the level number.

Open Settings and toggle Background music and Sound effects independently. Your choice is remembered next time you open the game.

Open Settings → Language and pick from the supported languages. The interface updates immediately.
