About this game

Stack & Merge is a quick, tactile puzzle about moving cards between four piles and merging matching ones into bigger tiles.

HOW IT PLAYS
Drag a card, or a short run of cards, onto another pile. If the card you grab matches the card it lands on, the two merge into the next tile up: 2 becomes 4, 4 becomes 8, and so on up to the 4096 crown. Merges can chain. When one merge creates a pair, the pair merges too, and the whole pile cascades with a rising run of sounds.

New cards arrive on a timer, or whenever you tap DEAL. If any pile reaches its limit, the run ends. There is no win condition: it is an endless run where you try to beat your own high score.

FEATURES
- Cascading merges with a distinct look and sound for every tile
- Three difficulty levels (Easy, Normal and Hard) that change which tiles appear, how full the board starts, and how many cards you can drag at once. Harder levels multiply every point you score (Normal x1.5, Hard x2)
- A built-in How to Play guide that explains the rules and power-ups
- Four card themes that change as your score climbs: Paper, Classic, Treasure and Mythic
- Four power-ups: Bomb clears the newest cards in a pile, Flip reverses a pile, Halve halves every tile in a pile, and Clear removes a single card. Each has its own animation and sound
- Power-up refills: watch an optional video for charges, or buy a pack
- Daily rewards: claim coins and power-ups every day, build a seven-day streak, and protect it with Streak Freezes that you can earn or buy with coins
- Leaderboards: see how your score compares worldwide and with players in your own country and its neighbouring countries, either this week or all-time
- Optional reminders: one evening notification if your daily streak is about to expire. You choose whether to turn it on, and you can turn it off at any time
- Music, sound effects and haptic feedback, each with its own switch

ADS AND PURCHASES
Stack & Merge is free to play. It contains ads: optional rewarded videos (for example to refill a power-up or continue after a game over) and short ads between some games. Optional in-app purchases sell power-up packs. Nothing in the game needs a purchase to play.

YOUR DATA
Your progress, coins and streak are saved to your device and backed up to the cloud under an anonymous player ID. If you choose a display name, it and your country (taken from your device's region setting) appear on the leaderboard together with your score. See the privacy policy linked on this page for details, including how to ask for your data to be deleted.
