8Eight is OpenFeint enabled.

+ Basic Control
If you tap the ball, the octagonal net that is trapping the ball will rotate counter clock wise by 180 degrees.
If you select and drag the ball, the location with adjacent ball will change. In this case, if the adjacent area is empty, the selection will be cancelled.
If the adjacent ball is same type with same color of connecting linker, the two net will be connected.
If you connect more than 3 nets, the net will be released and the ball will be free.

+ Round Rule
The types of ball and linker shall increase every 4 stages.
There are maximum 6 types of balls and 8 types of connecting linker.
In every round, the number of balls to set free will increase by one.
In the first, the time that one line is added is 12 seconds and it will decrease by 0.25 seconds every 2 rounds.
If the type of ball or linker increases, there will be no such reduction of time.

+ Mode
1. Fixed mode
When you tap the ball, octagonal net will rotate, but there is no change to the ball.

2. Face off mode
When you tap the ball, octagonal net will rotate and type of the ball also changes. In the case, the sequence of changing is regular, so it is better to memorize the sequence.

More mode will be added continuously.

+ Calculation of Point
Points will be added by multiple of 2 for the number of balls you set free.
If you set 3 balls free: 1+2+4 = 7 points will be added, and if 5 balls: 1+2+4+8+16 = 31 points will be added.
If the ball is set free, time bar will not decrease until other balls are rearranged.
In this period, "Combo Time" will be indicated on the top right side of the screen.
When set other balls free when it's "Combo Time", you can obtain accumulated points in addition to the previous points.
For example, when you set 3 balls free and set other 3 balls in "Combo Time", you get not just 14 points, but you can get 1+2+4+8+16+32 = 63 points.
In this case, the maximum point per 1 ball is 999 points.
