This small game has a slot machine mechanic combined with match 3. You can randomly roll rows and columns of gems and try to match them up. You can light up lamps for every gem matched (1 match = 1 lamp, 2 match = 2 lamps, 3 match = both lamps turn off). Any gem with two lamps lit up won't participate in the next turn (arm pull).
