The program ADDUP.PRG requires the file ADDUP.DAT and should
also be accompanied by this file ADDUP.TXT.
Blocks fall in groups of three. The object is to make 3
consecutive blocks add to 15 in either a horzontal, vertical, or
diagonal row. When this occurs the blocks dissolve and any
remaining blocks above fall downward. The second objective is to
avoid 3 consecutive blocks that add to 14. When this occurs the
blocks are marked with X and cannot be elimated from the game.
Start the game with the F1 key. Exit the game with Escape or
You maneuver the block group by the right, left and down arrow
keys, or you can use the J, K, L keys. The left arrow or J moves
blocks left, the right arrow or L moves blocks right. The down
arrow or K changes the order of blocks in the three group that is
falling. The space bar can be used to drop the group immediately.
The fall rate of the blocks is slow to give you time to look for
combinations that add to 15. Your time decreases as the columns
get higher increasing the difficulty.
Points are scored according to the numbers on the block
SCORE shows the score for the current game. X SQR shows the
number of X blocks in the playfield. BLOCKS shows the number of
blocks eliminated for the most recent fall. MOST shows the
largest number of blocks eliminated on a fall. TOTAL shows the
total number of block eliminated during the game.
A high score file is maintained so you must have your disk
unwrite protected in order for the file to be updated.
An alternate game could be played where the goal is to get the
largest number of X blocks on the playfield. The program has no
provision for retaining a list of these scores.
The program was made using GFA basic 3.50 and may be distributed
