Chain Merge

How to play

1. Tap a tile, then tap a touching tile with the same number to extend the chain. Diagonal neighbours count.
2. Tap the last tile of the chain again to merge. The merged tile is the next power of two that holds the total of the chain.
3. Tiles above fall and new tiles drop in. Every merge adds the new tile's value to your score.
4. A run is thirty merges. It ends sooner if no touching tiles match. Tap a tile earlier in the chain to shorten it, or Clear to start over.

Tips and strategy

• Long chains pay much more than pairs. A chain of five 4s makes a 32.
• Tiles that fall can line up new chains, so merge from the bottom when you can.
• Chains of three make the next power just above the total, so three 4s make a 16, which is more than twelve.
• Save a pair of high tiles near other high tiles so the next merge stays large.
