You want to play "strategy"? You're playing with sensitivity?

Update to Ver 2.0! It has been greatly refined and made easier to play.
We've redesigned everything, too!

Four in a row, done on a hexagonal board.
You win when you line up 4 of your pieces on the board in a horizontal or diagonal direction.
However, there is a special rule: "If you line up three, you lose".

Do you attack to get four in a row, or do you let your opponent get three in a row? Or you can make your opponent line up 3 in a row. To beat your opponent, you must attack with either of these two options.
If you think only of attacking, you may lose by three pieces in a row inadvertently. This is a game that requires concentration and calculation skills to read your opponent's strategy.
