Adapted from its popular namesake, this game is great for warming up both body and mind prior to training or competition.

The difference here is that players signal their moves with their feet. Standing with legs together represents rock. Legs apart equals paper and legs split to front and back means scissors.

To play the game, players face each other and use the fast feet action until the predetermined lead player - in this case, Kanamaru, suddenly adopts one of the three game stances.

Immediately the other player must decide which action will beat that stance and take that position as fast as possible. Make the right decision and they gain a point. Get it wrong, and the lead player scores.

As with the standard game, the same rules apply. Rock is beaten by paper. Paper by scissors and scissors in turn by rock.

Here is an example of the full game being played in its entirety. It can be repeated any number of times and players should switch who takes the leading role. Throughout the game, focus should be placed on maintaining balance and a strong upright posture, no matter the stance. As players grasp the concept and continuously select the correct winning move they should aim to increase their reaction speed.

The rules can also be changed up to add another level of complexity. The second version of the game is very similar. However, the player reacting to the initial move must now purposely make the wrong decision. Choosing what would be the losing move to score a point.

So in this scenario, rock beats paper, paper beats, scissors and scissors beat rock. In all three of these rounds, Uki scores the points.

Relating to judo, the scissors position replicates either a right or left natural posture. Paper replicates, jigotai, the defensive posture and rock replicates a weak posture.
