BLAM!PC Port

An arithmetic game for practising subtraction. Terrorists have filled a building with time bombs, and you walk into each bomb to disarm it by working out a subtraction: the top number minus the bottom number. Dial in the right answer and the bomb is safe; get it wrong and it blows up, with the right answer shown, and three blasts bring the building down. Each story must be cleared within five minutes, and each has ten more bombs than the one below, from 10 up to 60 across six stories. The skill level, 1 to 100, sets how big the numbers are. Stepping onto the blue line takes you up four rows, and walking off one side brings you round to the other.

Controls: Use either joystick. The stick walks; at a bomb, up and down change the digit under the cursor, left and right move the cursor, and the left button gives the answer. Before the game, up and down set the skill level and the left button starts. The keypad is not used.
