Tanjali

Tanjali is a very early Extended BASIC graphics memory game set on a 3x3 grid. The game has 3 skill levels, and 10 different viewing times (one of which is infinite until the player presses ENTER). The game will randomly populate the 9 squares with one of 3 shapes (square, triangle and circle) and each will be one of 3 random colors (cyan, magenta, orange). After the player's view time is up, the 9 squares are re-populated again and a little circular cursor appears by the first square. The player hits the Y or N key, meaning Yes this is the same shape/color that appeared in the original grid, or No either/both the shape and color are different. If the player guesses right, the square keeps the shape; if wrong the shape is blanked out. After each round (8 rounds are needed to complete a game) a bargraph for that rounds is added to the right side of the screen showing how many were right.

After all 8 rounds are complete, the player is shown the results screen, which shows which difficulty level they picked, score (shorter viewing times increases the point values) and two things that I am not sure how they work; "perfect score" and "percentage score".
