Math Blaster - Episode One

Now this is one I was kinda surprised about, I didn't expect to actually have some fun playing it. Definitely worth playing at least once for the lolz if nothing else, should only take about 20 minutes to get through the game. In Math Blaster your mission is to save your friend from that yellow alien jerk, with the power of math! The game is split into three phases. In phase one you're in space in your ship, and there is trash floating around with numbers assigned to them, you need to shoot the one that has the missing number to the equation below. In phase two you're on foot in a cave trying to reach the top, there are numbers on the sides of the spaces you need to pass through and it's up to you to make sure that the number you're holding is between the two numbers on either side by collecting water drops with positive and negative numbers on them. In phase three you face off against the yellow alien to rescue your friend, and the only way to defeat him is by going into the numbered hole on the bottom of the ship that correctly fills in the equation at the top.
