I think i ran into a glitch, i'm on wave 115, last thing i did with the truck was fix the fuel tank that had holes in it, and i've been in analize the situation for about 75 waves
so...i was almost done with the last ball, it being closest to the trashcan, i somehow accidentally droped it in the trash instead of being able to finish it, maybe don't have it so close to the balls
i only played the easy because i'm having an off day, but it is a good game, consider adding the ability to write notes in the boxes (possible numbers) and the hints need to be tweeked so that they don't go towards a box that has already been solved
Pres on the car after you have all the fuel
