Mahjong Solitaire: World Tour

Mahjong Solitaire: World Tour attaches a travel theme to tile solitaire. Solving levels moves you on to cities around the world, and the developer adds that the trip also runs through time, though it does not say which cities or which eras are involved.

On the board, one rule does most of the work. You remove matching tiles by tapping them, but only unblocked tiles can be picked. The developer defines unblocked carefully: a tile needs an open edge, and it needs nothing sitting on top of it. A tile that fails either test stays where it is until the tiles beside or above it have gone. No timer, hint system or level total is described, so this page leaves those questions open rather than guessing. It plays in a landscape frame at a standard widescreen size.

Look over the board for matching tiles that are unblocked. An unblocked tile has an open edge and nothing resting on top of it; any other tile cannot be picked yet. Tap the matching tiles to remove them. Keep going until the level is solved, and each solved level moves you on to a new city on the tour.

Check the two conditions in order. First look for anything on top of the tile, since a covered tile is out regardless of its edges. Then check its sides for an open edge. Tiles on the top layer at the ends of a row usually pass both tests and are the natural place to start.

Tile-matching mahjong solitaire with a world-cities theme, in a landscape frame. Tiles are removed by tapping, and only unblocked ones count. The developer frames progress as a tour through cities and through time.

Travel Mahjong Deluxe also has a travel theme, with a Hint feature and new layouts as you progress. Mahjong Bird Tiles defines its free tiles the same way: nothing on top and an open side.
