In ConSumo, you control a sumo wrestler, and your main goal is to eat your way to win. You have three lives. Your sumo can move in the eight cardinal directions. He cannot move off the edge of the mat, although if he is bounced off the edge of the screen by one of the other sumo wrestlers in the game he respawns in the centre with no penalties.
Articles of fresh and rotten food as well as puffer fish and other sumo wrestlers drift across the screen in straight lines. You must eat the fresh food to gain weight. As more weight is gained, your "weight gauge" gradually fills. Rotten food causes your weight gauge to decrease.
Each time it is filled, you become bigger, making it more difficult to dodge the hazards. The food and hazards also become bigger as well, and they fill or empty your weight gauge in increasing amounts the larger they get.
The other sumo wrestlers cause you to bounce away from them, which can send you into the pathway of rotten food or a puffer fish.
A puffer fish causes you to instantly lose a life. You can also lose a life if you eat rotten food when there is no room for your weight gauge to decrease.
As you progress in the game bad items will appear more frequently, such as blowfish, rotten apples etc.
There isn't much strategy. Get the good food and avoid everything else. It is safest to stay near the center of the playing field, so as to avoid getting hit by obstacles as they appear.
