Mahjong Collision

Nothing is lifted in Mahjong Collision. Tiles are dragged instead: push one in any direction and it slides until it meets another tile or the edge of the board, and if it stops against its own twin, both vanish.

That single change rewrites the puzzle. Position matters more than recognition, since you can see a matching pair all game and still never land one against the other, because every push also moves the walls that the next push will use. From the same group, there is also the Classic layout.

Eleven levels make up the main run, with the time allowed tightening as you go and leftover seconds converting into bonus points. An editor mode sits alongside it, holding 144 puzzles and letting you build shapes of your own. The same group of boards includes the Dream Pet Link board.

Originally a Flash release, it now runs as HTML5 in a desktop browser. Full screen helps more than it would on a stacked board, because a sliding tile has to be traced across the whole play area to see where it will come to rest. Connect The Dots Game For Kids sits one row away in the same list.

1. Drag a tile in any direction; it slides until it meets another tile or the board edge.
2. Bring two identical tiles into contact to make them disappear.
3. Plan the order, since every tile you move becomes a wall for the next one.
4. Clear the board to advance through the eleven levels.
5. Open the editor mode to build or practise on custom shapes.

• Build walls on purpose — in Mahjong Collision a stray tile is only a stopping point you have not used yet.
• Clear fast for the bonus — seconds left on the clock convert into points.
• Work from the edges inward — the board border is the one wall that never moves.
• Think two pushes ahead — a tile shoved into the middle can block a route you needed for the next pair.
• Use the editor to rehearse — with 144 puzzles in it, there is room to practise the awkward geometry.
