• Basic mode
Various sizes of boards are prepared; 2 by 2, 2 by 3,...8 by 8. You can
select one among them and play! Stage starts with 1-1 and two '1' blocks
are placed on the board. Now, '1/n' blocks appears 'n' times repeatedly for
n=2,3,4...sequentially and this means you must make the number '1' by
merging every n '1/n' blocks! Otherwise, unmerged blocks occupy the
board and you will be gradually close to Gameover. If no blocks can be
moved, the game is over and the number of stage will be your score. So,
be careful to your choice and think every time to verify which is better for
making a larger free space!
