Domino spider, duel

1. Each player gets seven tiles; the lowest double starts in the center.
2. Add tiles to whichever of that first double's four sides they match, then to the open ends.
3. No playable tile? Draw from the boneyard until one fits or it runs out.
4. After placing a double you may close it, blocking that end.
5. Play your last tile to win the round — if the layout blocks, the lighter hand wins.

Domino spider, duel is a head-to-head domino game where the layout spreads out in four directions instead of a single line. Each player starts with seven tiles, and the lowest double opens the game in the middle of the table; tiles can then be laid on all four sides of that first double. If you can't match an open end, you draw from the boneyard until something fits or it runs out. Doubles add a tactical choice: after placing one, you may close it and shut that end for good. A round ends when someone plays their last tile — the pips left in the loser's hand are counted against them — or when the layout is blocked, in which case the lighter hand wins. Play against the computer or an online opponent.
