Dominoes

Classic double-six dominoes against the AI. Match a tile to an open end of the line, draw when you are stuck, and be first to empty your hand. Beat the AI and build a win streak.

How to play

You and the AI each draw seven tiles; the rest form the boneyard. Take turns adding a tile to either open end of the line.

A tile is legal if one of its two numbers matches the number showing at an open end. Tap a playable tile to lay it down; if it fits both ends, tap the end you want. The first tile of the game can go anywhere.

If you have no legal tile, tap Draw to take from the boneyard until you can play. When the boneyard is empty and you still cannot move, your turn passes.

First to empty their hand wins. If the game locks up with neither side able to play, the lighter hand โ€” fewer total pips โ€” wins. Each win extends your streak, which is your score.

Tips & strategy

Count the suits, not just the tiles. With seven dominoes you usually hold a glut of one number and a shortage of another; steer the open ends toward the number you have many of, and you will keep playing while the AI is forced to draw. The whole game is a quiet fight over which two numbers sit at the ends.

Doubles are the trap tiles, because they only ever match one number and they cannot change an end. If you are holding the double-five, you can only shed it when a five is showing, so play your other fives sparingly and keep a five available rather than blocking yourself out of your own heaviest tile.

When you cannot empty your hand, plan to lose light. The blocked-game tiebreak is total pips, so when the board looks like it may lock up, dump your big tiles โ€” the six-six, six-five, six-four โ€” early, even if a lower tile would also play. A hand of small leftovers wins stalemates that a hand of heavy ones loses.

Watch what the AI draws. Every time it goes to the boneyard it has told you it lacks both end numbers, so if you can keep both ends on the numbers it just failed on, you choke its options and force more draws. Late in the hand, denying the suit it needs is often worth more than rushing your own count down.
