Slide rows and columns of ENs to line up more than three same-colored ENs. Puff, they disappear and remaining ENs fall down according to the laws of gravity. If they line up again, COMBO! You get double, triple scores or more.
Sliding ENs without removing them causes a penalty and makes scores reduced. Taking too much time and you will be run out of time. So, be quick, nimble and strategic.
4 game modes:
[NORMAL] Remove as many ENs as you can till you run out of time. Removing ENs earns a bit of additional time.
[120 SEC] 120 seconds time limit with no extention.
[50 MOVES] You can move 50 times in no hurry. Sit back and plan for super combos.
[30 VS 30 ] Two players. 30 moves each to beat the opponent. No EN required.
Each EN you earn can be spent on Magic Items which can boost up your score. Every EN you remove earn you ENs or you can buy them.
By the way, 'EN'(pronounced yen, not in) means both 'circle' and 'Yen'(currency) in Japanese.
