Each turn players alternate being ‘bomber’ or ‘diffuser’ and reveal their moves simultaneously.
A bomber can choose to immediately bomb by revealing 10 fingers, or reduce their timer bomb by 1 finger (timer starts at 9 fingers). If a bomber manages to get their timer to 0, their timer bomb may go off any number of times. If a bomber successfully sets off either bomb, they win.
The diffuser can either diffuse an immediate bomb by revealing 10 fingers, or stall their opponent’s timer by revealing 0 fingers.
