This is a fantastic game. The introduction is clear and easy to follow. The different skill levels allow people like me (who are not good at the game) to enjoy playing easier levels while allowing skilled players to have a bit of a challenge. The graphics are clear and easy to understand (I am so grateful for this - my eyesight isn't the best). It's just a really solid, fun, game that gives me the 4x experience in a short bite-size game.
