49Chain Support
49Chain is a number puzzle with chain reactions, published by Codex Leo AS. Drop numbered tiles into a 7x7 board and connect as many equal tiles as the number on them: two 2s, three 3s, four 4s. When tiles fall and form new groups, those clear too, and every cascade step multiplies the score.

Frequently asked questions
The game asks me to watch an ad to continue. Is that required?
No. When every column is full you can choose to watch one rewarded ad, which clears the top tile in every column and lets you carry on once per game. You can always start a new game instead.
Why do tiles not connect diagonally?
Tiles only connect up, down, left and right. A diagonal neighbour never counts towards a group.
How do I change the language?
