All you have to do is find the matching cards. Sounds easy, right? Well, it would be if Simon hadn't released a swarm of Muck Beetles to mess with your game. Somebody even said they saw a Muck Dragon flying around, so watch out!
Match 2 cards with the same picture to remove them and score points. Left click a card to flip it over. Click another card to look for the pair. You may only have 2 cards flipped over at one time. Find all the matches in each round before the time runs out. Complete pairs before the muck beetle swarm devours your cards! If a muck beetle eats one card, you lose the pair and lose points at the end of the round. Match a pair of anti-swarm cards for one anti-swarm point. Click the anti-swarm button to shoo away a swarm of muck beetles. Watch out for the muck dragonhe'll scramble your cards!
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
