Players should open up new tiles with every pair they eliminate. Haphazardly choosing obvious pairs, such as those from the top levels, will often end the game prematurely (i.e. lose) by leaving essential tiles under cover.
In most Mahjong solitaire games there are four tiles for each character, flowers, trees, animals, people, seasons and other images are different and usually have one of each kind; you can match and remove tiles of the same category (tree with tree, flower with flower, etc.)
There is a strategy to complete the game, it is better to be selective and remove the tiles that will open open options, and not the ones that will block the game.
