SumoscienceAR is a game for people who want to learn more about sumo. It models the physics (forces/collisions) between the wrestlers. You can do a frontal pushout, belt pushout, slapdowns, and throws. You can practice in the sumoobeya or try your skills in an oozumoo tournament. In the sumoobeya, you can change the attack style and level of your opponent to practice how to deal with certain attacks. You can also select automatic play to watch the computer play itself.
In the game, you are the wrestler with the yellow belt. On the right side is a first person view of your opponent with buttons for various attacks.
1) Chest attack: Press the red button the push the chest. You need to be moving forward for this to be effective.
2) Slapdown: Drag down the yellow button and your arm will reach for their head and attempt to pull them down. After your arm makes contact with their head (button turns blue), you need to move backward to give more force to your pull. This only works if your opponent is moving forward.
3) Grip Belt: You can press the green buttons to reach for the belt. When you have a grip, the button will turn blue. You can push them out of the ring. If you have a two hand grip, you can sometimes lift them. You can escape from this grip by turning quickly.
4) Throw: Once you have a grip, you can turn quickly to the side opposite your grip. Once you are facing the same direction, you can step forward to throw them.
5) The forward and back buttons are on the left. The turn button is in the middle of the first person view and it must be dragged left or right to turn.
SumoscienceAR attempts to mimic some of the difficulties in real sumo. Slapdown are relatively easy to do, but not always successful, because they depend on your opponent's movements. Throws are a powerful move, but they require the coordination of multiple movements and can be countered by turns or grips of your opponent. The chest push is an easy move, but you need to keep your opponent in front of you and avoid slap downs. It can be hard to grip the belt initially, but it gives you a lot of control over your opponent. But if they also grip your belt, then there is not much advantage for either side. As in real sumo, moving forward and keeping your opponent in front of you are the basis of a good technique.
Although we attempt to make the physics realistic, it is pretty hard to deal with every possible situation and sometimes you will have strange situations that are fun to watch (e.g., flying sumo wrestlers).
The sumobeya room is free, but the AR and oozumo rooms are only available for two weeks. After that, you need to support the app to use them.
