Objective: find pairs of tokens to clear the board.

Click the empty board to let the system create a random setup of partially overlapping Mahjong tiles.
The Mahjong tiles used here are three different suits numbered 1 to 9, which are called simple tiles.
They are bamboo, characters (or myriads), and circles (or dots).
Usually there are four matching tiles for each value (e.g. there are four dot tiles with the number 2).
In this Zillions game the amounts of matching tiles for each value vary.

Click two matching tiles to eliminate them.
The tiles are sensitive for clicking only at the top left (the 'hand' cursor will appear when you can click).
You can only click tiles that are not partially or totally covered by another tile.

If you click an uncovered tile that does not have an uncovered companion, you lose.
You also lose if there are still token on the board, but you have no move left.
You win when you have cleared the board.

Variants 1 to 6:

The variants 2 to 6 use more tiles and/or a larger board.
Variants 1 to 6 are easy variants because you can lift out a piece when is has neighbors on both (left and right) sides.

Variants 7 to 12:

The variants 7 to 12 have the same setup as variants 1 to 6, but one more restricting rule:
You can only lift out a tile if it has no neighbor at the same level, contacting it on the right or on the left or at the top or at the bottom side.

Variants 13 to 18:

This is the full-blown Mahjong version.
The variants 13 to 18 have the same setup as variants 1 to 6, but one more restricting rule:
You can only lift out a tile if it has no neighbor on the right or no neighbor on the left side.

Note that not all setups are solvable. This is true the more so for variants 13 to 18
