Dominex is a free daily domino strategy game where you face an AI opponent across three difficulty levels. Using a standard double-six set of 28 tiles, you take turns placing dominoes end-to-end on a shared chain, matching pip values to extend the line. The goal is to empty your hand before the AI does — or end the game with the lowest pip count when neither player can move. If you enjoy domino puzzle games like the NYT Pips game, you'll feel right at home with Dominex. It brings the same satisfying domino brain teaser experience to your browser — completely free, with no account required and no data collected. Unlike many online domino games cluttered with ads, Dominex is clean, private, and works offline. Dominex is part of PuzzleBoxs, a collection of 10 free daily puzzle games. Each day's tile shuffle is seeded by the date, so every player on the same difficulty faces the same game — share your results and compare strategies!
How to play Dominex: You and the AI each start with 7 tiles drawn from a shuffled double-six set (28 tiles total, numbered 0–0 through 6–6). The remaining tiles form the boneyard draw pile. On your turn, select a tile from your hand that matches either the left or right open end of the board chain — click the arrow buttons to choose which side to play. If no tiles match, tap "Draw Tile" to draw from the boneyard until you can play (or pass if the boneyard is empty). The game ends when a player empties their hand (they win the sum of the opponent's remaining pips), or when neither player can move (lowest pip total wins). Higher pip values in your hand hurt your score, so play strategically!
Dominex is inspired by daily domino puzzle games like NYT Pips, but it's a completely independent game. Unlike the NYT version, Dominex is entirely free, requires no account or subscription, collects zero data, and works offline.

You and the AI each start with 7 domino tiles. Take turns matching tile ends to either side of the shared chain on the board. If you can't play, draw from the boneyard. The first to empty their hand wins — or if both players get stuck, the lowest pip count wins. Select a tile from your hand, then click the left (←) or right (→) arrow on the board to place it.
Dominex offers three difficulty levels: Easy (AI plays a random valid move), Medium (AI prefers tiles with high pip values to minimize its hand score), and Hard (AI uses an alpha-beta minimax algorithm with lookahead — a genuine strategic challenge). You can switch difficulty at any time to start a new game.

Pips are the dots on a domino tile that indicate its value. A standard double-six domino set has tiles numbered from 0 (blank) to 6 pips on each half, for a total of 28 tiles. The total pip count of your remaining hand at game end determines your score — the goal is to finish with as few pips as possible.
