Troika

In a not so distant future, scientists find very special stones on another planet. If you collect three matching stones, you can turn them into an extremely valuable gem or into fuel.

After hearing about the stones, you decide to travel to this new planet to become rich. You arrive safely, but after having some troubles on the way, your spacecraft is now out of fuel. What a dilemma! You want to make valuable gems, but you also need fuel to get back to Earth. You're also not the only person with this idea. Can you collect more gems than the others and still escape from the planet?

In this game you have to turn the face-down tiles lying on the table one by one. When it's your turn, you also have to collect one of the tiles, no matter if face-up or face-down. That's all you need to do in this game.

The game ends when all tiles are turned face-up and until then you have to try to collect as many trios of consecutive numbers as possible. You also need to collect a trio of the same number, a socalled "fuel-set", or you won't be able to go back to Earth again...
