Read full description

With each move shift the coins on the board in one of six possible directions. Two equal coins merge to the next higher value. The highest coin value is 2 EUR. If you merge two 2 EUR coins a 5 EUR note will appear. If you merge two 500 EUR notes a 1000 EUR gold bar will appear. Will you make it to the gold bars? That is quite hard but it is possible if you strictly follow the right strategy. Maybe you even make it to the final goal, a 10.000 EUR gold bar? That is possible!
