About Block Dominoes: Onyx Night
Block Dominoes: Onyx Night is the tense, no-safety-net way to play: black onyx tiles with bright white pips on a midnight blue table, and no boneyard to rescue you. Everyone receives seven tiles and that is all you will ever have. Match an open end if you can; if you cannot, you simply pass, and every pass tells the table which numbers you are missing. That information is the whole game. Strong players hoard the numbers others lack, lay doubles before they get stranded, and steer both ends toward suits that will lock their rivals out. When the line blocks completely, the player with the fewest pips in hand wins the round, so dumping heavy tiles early matters too. Win a round to collect every pip left in your opponents' hands and race to 100 points. Play with two, three or four at the table against Easy, Medium or a ruthless Hard computer, or sign in and face real people online. Smooth 3D tiles, glowing playable pieces and hints make it easy to learn and hard to master.
How to play
Tap a glowing tile to play it on a matching end (tap the end if both fit). There is no drawing: if nothing fits you pass automatically. Empty your hand, or hold the lightest hand when the line blocks, to win the round. First to 100 points wins.
