The destruction will also leave a gap when you destroy balls that are located in the middle of the line. The destruction will create a chain reaction if the adjacent balls are of the same colors. If the color matches, the target will be destroyed. You have to prevent the balls from reaching the end as it will be a game over when it happens. If the color doesn’t match, the fired ball will be added to the line of balls that surround the frog, which makes the line of balls gets longer and closer to the hole at the end of the pathway. For example, if the ball that comes out from the frog’s mouth is blue, than you must fire it at a blue ball. The color of the fired ball must match the color of the target. You have to destroy the oncoming line of balls by firing colored balls.
There are only two things you can do with the frog: rotate it in any direction and spit colored balls from its mouth. In this game, you are a frog and your enemies are colored balls.
