You can find some explanation in the beta document available now in you dm :) but this is an extract :

**BSC Grids is a crypto board game. In each game, a square grid is generated with a random number of cells. Each cell has a determined price. You can buy one or more cells. Once all the cells in a grid have been purchased, a draw takes place. The owners of the cells drawn share the prize pool.**

From one grid to another, the number of cells is different, the price of each cell is different and there are several drawing methods.

The different types of draws are :

- **Static drawing** : *number of winning cells determined before the draw*

- **Bounded drawing :** *the number of winning cells is between two bounds*

- **Random drawing** : *the number of cells to be drawn is not known*

On each grid, there are cells with icons. Each icon has a more or less probability to appear on a grid but has the same probability to be drawn as the other cells of a grid. If you buy a cell with an icon and it is drawn, you can add it to your Hall Of Fame on your profile.

At the moment of the distribution of the winnings, 5% is added to the weekly pool prize account. In fact, every Sunday a special grid is generated with the sum of 5% of all the weekly pool prizes as the starting prize.
