About this game

Pieces enter from any of the four sides. They slide, and they dock in the last empty cell before whatever is already there. You choose the line. The board chooses the cell.

Three in a row clears — but only when every attribute is all-same or all-different, judged one at a time. Colour, shape, number, and deeper in, the direction a piece faces.

There is no gravity. When a piece leaves, the hole stays exactly where it was, and a hole in the middle of a line cannot be reached from either end. The board you are playing on is the board you made.

HOW IT PLAYS

• Three pieces wait in the rail. One is active — tap another to switch.
• Drag off any edge to send the active piece in from that side.
• It slides until something stops it, and docks in the last free cell.
• Make three in a line where each attribute is all-same or all-different.
• Stuck? Tap a docked piece to pull it back, if its path to an edge is clear.

Out of 1,259,712 possible triples, 20,412 clear. About one in sixty. Finding one is not luck.
