Red Reactor is a simple yet exciting 2 player game that is based on the classic game of Slap Hands. It is a free game developed by Castle World War that is compatible with Android 9.0. The game is designed for girls and boys who love to play reaction games and challenge their friends to see who has the fastest reaction time.

The game is played by two players who stand on opposite sides of the device. One player becomes the attacker while the other becomes the defender. The attacker's goal is to tap the defender's hand before the 10-second timer runs out. If successful, the attacker scores a point and continues to attack. If the defender retreats without attacking, they lose a shield. The first player to reach 10 points wins the game.
