Once you join, the game will wait for enough players to gather or fill the empty seats with bots. After a quick countdown you will have to solve the first task, e.g.: 5 + 9.
The faster you solve the equations, the more points you get and the higher you climb. Players that reach the top, will push everyone (them included) a couple steps back. The water level will slowly rise from the bottom, players that touch the water are eliminated.
The last player standing will win, good luck and have fun!
