TriTryst is a game comparable to Tetris - or even more to columns. You have to put marbles of different colors on a empty field and try to get 3 or more in a row. Different to tetris or Columns TriTryst doesn't have gravity neither a time limit (in Normal mode)
The game contains a normal and an arcade mode, and it contains over 20 levels - which means different shapes of boards as well different bonus tiles. Though sadly there is just one general highscore list for all types, with only 5 possible entries.
