Your mission is to collect gems into the wagon with the same color of gem signed on the wagon. You should avoid collecting bad gems into wagons.

Two numbers on each wagon indicate: (1) how many right gems you have to collect | (2) how many bad gems you can collect

1)
You have to collect the right gems until the wagon's first number drop to the value 0.
If you reach the number 0, the wagon is full and you cannot collect bad items anymore. If you collected any bad item, you would lose the game. Into the full wagon is allowed to collect the right gem (but it is not necessary anymore because the wagon is full) or dynamite (but you can destroy the gem and then you need to collect the gem again).

When all your wagons reach the value 0, you will win the game.

2)
You should avoid collecting bad items, but some wagons can have got also a space to collect bad items. Any item except the correct gem and dynamite is classified as a bad item.
If you would collect into the wagon with a value of 0 for collecting bad items any bad item, you would lose the game.


The wagon can be moved by touching the finger and moving left or right. The wagon can move out of the screen. The wagon cannot push another wagon that is not connected to the wagon except for wagons placed in the safe area.

On the left and right side of the screen is a safe area marked by a darker color. In this area do not fall down any items. If the wagon or group of wagons is wholly placed into this safe area, it can be pushed away by another wagon.

Each level is randomly generated.

You have to fill all wagons with the right gems. It means the first value on the wagon has to drop to 0.
