About Domino Chain
Domino Chain asks you to place every domino into a single line where touching halves show the same number. Tap a domino and it attaches to either end of the chain, flipping if needed. Every level is built from a real chain, so a full solution always exists.
How to play
- Tap a domino from the tray to add it to the chain.
- Touching ends must show the same number.
- Use every domino. Undo the last piece if you get stuck.
Tips and strategy
- Start with a domino that has a number appearing rarely.
- Count how many times each number appears: odd counts mark the chain ends.
- Doubles can be slotted in whenever their number is exposed.
Levels, stars and XP
Finish a level to earn one to three stars and XP towards your player level. Replay any unlocked level to improve your stars. From level 151 the game enters endless mode, where each level is a remix of an earlier one with fresh colours and a slightly higher difficulty.
