Board game Funny Jumpers

Each player receives a set of five balls. On command, all players must try to throw their balls into the cube, so that they ricochet off the table surface, falling into the holes of the cube. You need to get rid of all the balls as quickly as possible before the separating pyramid inside the cube delivers them back to the trays. The first player to succeed closes their tray and is the winner! You should always pick up and throw balls with one hand only. You can throw balls into the cube through the side hole on your side or by ricocheting through the hole at the top of the cube. You cannot throw balls through the holes of other players. If four players are playing, there is no need to block slots.
Progress of the game: Agree to start the game. For example, the command could be the phrase “GO!”, after which each player throws their balls into the cube, trying to clear their tray as quickly as possible.
If a ball falls to the floor, the player who dropped it must pick it up and return it to play as quickly as possible.
The first player to empty their tray and close the door is the winner.
