The game is based on a simple premise. Mathematical IQ related questions appear on blocks which move from top to bottom of the screen. Before they hit the bottom, you need to select the correct answer out of the three choices available. If a block hits the bottom it stays there reducing the time you have available to answer the questions on subsequent blocks.
The game has different playing levels:
Easy - 2 digit addition, 2 digit subtraction, 3 digit addition, 3 digit subtraction
Normal - 2 digit multiplication, 2 digit division, Ratio, Percentage in addition to Easy
Hard - Squares, Cubes, Square Root, Fractions in addition to Normal
Points allocated are:
Easy : 4 for correct answer, -2 for incorrect answer
Normal : 8 for correct answer, -4 for incorrect answer
Hard : 12 for correct answer, -6 for incorrect answer
Every fifth block is a magic block which, if answered correctly, clears the screen thereby increasing the chances to get a big score.
Have fun playing the game!!!
