The game consists in flipping falling black and white coins so that they all end up black when they reach the bottom of the screen.
The game is set in a simple interface. There's a forbidden zone in the center of the field, marked red. In this one, the player cannot flip the coin, but the computer can.
From time to time a power up may appear, in the shape of a blue circle with an "H" inside - this item establishes barriers at both sides of the zone that sets the coins in a superposition (half black, half white) state. It seems clear after a while that the first barrier sets the superposition, and the second one turns things back into normal.
The Objective
The hidden objective behind this apparently innocent game is to show some quantum concepts relevant to quantum computing:
The coins represent qubits, with its colors accounting for the states |0> and |1>.
Touching the qubit equals applying a NOT gate, thus inverting its state.
The blue "H" power up is the Hadamard gate, which sets the qubit in a superposition state. Since the Hadamard gate is its own reverse, the double application of the gate returns the qubit to its original state.
The game is also based on an actual quantum game theory algorithm, so it is useful towards its understanding.
