So you're a knight and there's this nasty dragon in a dungeon and you need to get rid of it before it eats you or burns you or burns you then eats you or whatever dragons do these days.
It's not a very original premise anyway. But don't let that put you off this puzzle game because it's really quite good fun.
Each level finds you with a puzzle of pieces including a dragon's head, eagles, unicorns and shields.
You need to rearrange the board so that the dragon's head, which doesn't look very scary, can drop into the black hole on the floor of the room.
Then you go on to the next level and do it all again. There are 21 levels in total which get harder as you go on and you can stop and return to the game at any point.
