This is an ancient board game which dates back to the 6th century AD, and your target is to gather as many pieces of gems in your store as you can. On the game board, 12 small pits are divided into 2 rows, and each of the pits contains 4 pieces of gems. The upper row of pits belongs to the computer, and the lower row is yours. The 2 large pits on the left and right of the board are the stores, with the one on the right belongs to you, and the one on the left belongs to the computer. You and the computer will take turns to move the gems, and each time you may click any of the pits on your row. When a pit is selected, the gems inside will be distributed one by one to the next pits in counterclockwise direction. If the last gem of a move lands on your store, then you can take one more turn by selecting another pit. If the last gem of a move lands on an empty pit on your side while the opposite pit contains gems, then you can capture all of the gems in both pits and put them to your store. The same rules apply to the moves made by the computer. When the pits on one of the rows are emptied, the game ends. The remaining gems on the pits belonging to you will be counted as yours, and those on the pits of the computer will be counted as the computer's. Capture the gemstones with tactics and win prosperously!
