Holiday Mahjong Dimensions

Holiday Mahjong Dimensions is the Arkadium cube dressed for December. The 2020 edition swaps the geometric faces for Christmas trees, strings of lights and tree ornaments, and puts an entirely new set of levels behind them, scored to Christmas songs rather than the usual ambient loop.

Underneath, the block behaves exactly as the rest of the line does: multi-layered stacks of cuboids, a match only when both tiles are clear of anything on top and open on a side, and a rotation control that turns the whole structure so you can read the back. What the festive art changes is legibility, because a bauble and a tree read differently at a glance than two similar abstract patterns, which makes this the friendliest cube in the family for a first-time player. For one more rotating board, see Black and White Dimensions.

The clock still runs per level, and hint and shuffle are on hand when the exposed faces stop producing pairs. Quick consecutive matches pay combo bonuses, so the tempo that scores well is the same one that clears the board. If the layout is new, the guide to rotating boards explains it.

The stage is 640 by 480, and full screen is worth using: the ornament tiles carry fine detail that a small window flattens. Rotating before matching is the habit in Mahjong Flower Tower too.

1. Rotate the block to bring every festive face into view.
2. Pick two identical tiles, whether matching trees, matching lights or matching ornaments, that are free on top and on one side.
3. Remove the pair with two clicks and keep the layer peeling.
4. Clear the full set of tiles before the timer runs out to move on to the next holiday level.

• Read the ornaments closely — several bauble designs differ only by pattern, and a wrong click costs tempo.
• Chain the matches — consecutive quick pairs earn combo bonuses on top of the base score.
• Save the hint — it is worth more on a thinned board than on a full one where pairs are everywhere.
• Spin often — each removal changes what the hidden faces show, and the back of the block fills with options.
• Enlarge to full screen — the fine detail on the Christmas tiles is what you are matching, and 640 by 480 hides it.
