Rule

1.
You and your opponent put a piece which they take from the left tray on the center board by turns. The piece's number as it is added to the score, so you had better put bigger number basically.

In this case, you can put 5 or 6.

3.
When there is no piece putting on one space, an all-mighty piece is put on automatically. The all-mighty piece becomes every number, so this is a chance to put a big number.

Technique

1.
In this game, the first mover usually wins because he can put bigger number in advance. For the second mover, thinking to fill the difference in points is important.

2.
The last piece of the round adds double of that number. This rule sways the game. If you want to put the last one, you had better to think about all-mighty's number. When you are the first mover, you should make all-mighty's number to odd. Of course the second mover should make that to even.

3.
Thinking only the present situation brings losing to you. Think the future, and put the best piece on the best position. Sometimes putting small number comes the opponent's disadvantage.

4.
To win over the computer by a big difference, you had better reset default pieces over and over, to your content. When you play a game with somebody, you should reset to obtain your opponent's consent.
