About this game
Domino Effect is a merge puzzle. Place a domino so its number touches the same number, and the two merge into the next value: 1+1 makes 2, 2+2 makes 3, up to 6. Every merge can set off the next one, so a single domino can rewrite the board and send your score flying. No timers, no lives.
FIVE WAYS TO PLAY
• Classic: an endless board, just your best score
• Levels: hundreds of puzzles with goals, move limits and modifiers. New ones added regularly
• Remix: the rules change as your score grows
• Chess: pieces instead of numbers, each one merges the way it moves
• Gravity: tiles fall as soon as there is room below. Unlocks as you progress or with a purchase
ALSO
• Boosters: bomb, hammer, lightning and shuffle
• Letters: chains drop the letters of DOMINO and EFFECT, a full word doubles your score
• Skins: mahjong, cards, fruits, donuts, neon, wood
• Autosave: pick up exactly where you left off
How to play
1. Drag a domino onto any free cell, with the mouse or a finger
2. Tap the domino to rotate it
3. Put matching numbers side by side and they merge into the next value: 1+1 makes 2, 2+2 makes 3, up to 6
4. One merge triggers the next: that is a chain. The longer it is, the more points
5. Two sixes merge and vanish, that is how you free space
6. Out of moves? Use a booster from the panel to the left of the current domino
7. In Levels, complete the goal within the move limit and watch the modifiers
TIPS
• Look at the next domino before placing the current one
• Keep a couple of cells free, a crowded board leaves no room to maneuver
• Push values up: merging fives and sixes pays the most
• Boosters drop from combos and level goals, do not hoard them forever
