Pictoquest – the developers call PictoQuest “logic puzzles with an easy turn RPG”. In fact, this is a project in which the main game mechanics is solving Japanese crosswords. As in some Empires & Puzzles you need to solve puzzles three in a row to fight with enemies, here you need to use such mechanics. If you do not know how to do it correctly, then the game will probably be learning, and the process itself is much more interesting than the same three in a row and really makes the brain work.
