Enjoy the chain reaction of sand pile model

‘sand pile model’ is an iOS app that enjoys chain reactions.

The longer the chain reaction, the more scores you will get.
Creating a long chain reaction with a small amount of power (number of taps) is the key to increasing the score.

When all the cells disappear, the stage will be cleared and you will move to the next stage.
As the stage goes up, the difficulty level goes up.

Power will be added when the stage is cleared. Power can also be increased by looking at ads.

It’s easy to play.
The guide will be displayed at the first startup, so please have a look.

Download the free app ‘sand pile model’ from the App Store.

You can start the guide as soon as you launch the app.
The guide will start automatically only for the first time.
The guide may seem a bit complicated, but in reality it’s easy and intuitive to operate.

If you tap the cell of ‘1’, it will change to 2 and the score will be added.
Since you tapped once, the power is reduced by 1.

If you tap the cell of ‘2’, it will change to 3 and the score will be added.
Since you tapped once, the power is reduced by 1.

Tap a cell is the only operation that consumes power.

If you tap the cell of ‘3’, it will change to ＊ and the score will be added.
Since you tapped once, the power is reduced by 1.

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.
Since you tapped once, the power is reduced by 1.

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.
The star reaches cell ‘1’ and changes cell ‘1’ to cell ‘2’.
Since you only tapped once, the power is reduced by 1.

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.
The star reaches cell ‘2’ and changes cell ‘2’ to cell ‘3’.
Since you only tapped once, the power is reduced by 1.

A star sends a tap operation to the destination cell without consuming power.

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.
The star reaches cell ‘3’ and changes cell ‘3’ to cell ‘＊’.
Since you only tapped once, the power is reduced by 1.

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.

The star reaches the primary destination cell of’*’ on the top, bottom, left, and right, and the primary destination cell disappears. Furthermore, stars are also emitted from the primary destination cell in the vertical and horizontal directions of the primary destination cell. Similarly, the stars emitted from the primary destination cell will send tap operations to the secondary destination cells up, down, left, and right.

Since you only tapped once, the power is reduced by 1.

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.

Since you only tapped once, the power is reduced by 1.

Scores are added when cells grow and when they disappear.
The “amount of score to be added” increases with each chain reaction.
[ chain reaction : a star reaches a cell of’*’and emits more stars from that cell ]

When you tap the ‘＊’ cell, that cell disappears and stars are emitted in the vertical and horizontal directions.

This pattern grows all cells to ＊ and eventually disappears. If you are in the game, this will clear the stage.

(The current “amount of score to be added” is displayed on the left side of the score display)

Since you only tapped once, the power is reduced by 1.

The guide ends with guide 10.
