Mammon (God of Wealth) is a classic street game in the East. Players place "treasure" (usually a coin) on a table and under one of the three cups on that table. Then they mixed up the position of the cups really fast. Once stop, one player will guess under which cup the treasure is. On the street, to participate in the game, players must pay an amount of money and if guess correctly, they will be rewarded more (probably double) the amount paid.
Games "Diamond Hunter" is based on the idea of that game. Of course the players do not have to pay money but have to pass 5 levels, each level with 5 sub-levels to find a large diamond! The game is over when one of two conditions is met:
1) The player wins, the biggest diamond is found, or
2) Wrong guess for more than 5 times.
The game is simple, still it helps you exercise your memory and focus while the cups are moving. The levels will get harder in order: faster and more complex motion! Challenge yourself in finding your giant diamond!
