All you have to do for level 4 (if you can't reach that, switch to Chrome or Safari) is just start a tower maze, then call in wave 1 and let them do whatever, then spam-call the other 14 waves, place Heavy Noob II as some of the maze for as long as you can afford, then, as enemies die, use Nooby to finish the maze
Formula:
(overall rank)^2 x (average of how much monster meets requests/100)^2 x 4
* For stuff like mating, incubation, & how much it eats, it takes the reciprocal and doesn't divide by 100
Overall ranking throws the clients' offers all askew.
"I'm looking for a monster that has low incubation time and doesn't eat much." 216 for 2 days and 5 kg, 324 for 2 days and 7 kg?
