Extreme Animal Jumping is a very profitable board with 4 upgrade branches, nearly as profitable as Extreme Lawn Mowing.
Extreme Animal Jumping has four upgrades that all help the DPS output of the board entirely
Crossing Bonus - 39 Million ~ (20 upgrades)
Jumping - 42 Million ~ (20 upgrades)
Animal Frequency - 55 Million ~ (10 upgrades)
Jumpers - 58 Million ~ (10 upgrades)
Crossing bonus affects the amount of profit that the animal recieves when it succesfully reaches the spikes on the other side
Jumping affects the amount of profit made when a jumper jumps up, each jumper gets this bonus
Animal frequency affects how rapidly the animals come out resulting in more animals reaching the other side and the more times the Jumpers jump
Jumpers act as a multiplier to both the Crossing bonus and the amount of money recieved from Jumping
All of these upgrades work fabulously together making DPS reach nearly the levels of the Lawn Mower
It's best never to actually play this board on your own, the board AI will not allow for mistakes and will let the animals cross the board succesfully every time, you should only access the board if you wish to upgrade the board or have a strange nag to play it.
