Math-A-Magic! / Echo!
Synopsis
Math-A-Magic! is a “professor of electronic arithmetic”. The player can choose up to three variations of math games.
In the first variation, the player will have to solve regular math problems. He first chooses the type of operation (addition, subtraction, multiplication or division), then the skill level (1-3) and is then presented with the problems. He must type in the answers, and the computer will record the time elapsed and the number of current problems solved. If the player fails to solve a problem twice, the game is over.
The second variant presents algebraic problems. The player selects the desired skill level (1-3) and must enter the missing variable for each problem, and the rules are the same for the first variation.
The third variation is an addition or multiplication table game. The player chooses addition or multiplication, then the number he wishes to practice.
Echo! is a basic Simon game (invented by Ralph H. Baer). Four colored numbers (red, blue, green and yellow) will appear on the screen. One of them will light up, and a sound will play. Then it's the player's turn: he must match the lit number. Then the first number will be lit followed by a second. The player must match the sequence and it will continue to increase indefinitely. If the player fails three times to match a sequence, the game is over.
