Donut Farming[]
The players must be at least Level 50 and 200% XP and cash bonus to do donut farming. Here's the way to farm donuts and remember, don't forget to activate XP multiplier charge into XP Collider.
Kwik-E-Mart (220-14,400 cash): Efficient, but slow.
Bloodmobile (132,000 cash) or Rat Trap Delivery Truck (150,000 cash): Quickest, but expensive.
NOTE: Don't place too many items which lead the game would be disconnected from the servers and your cash will be lost.
Placing vehicles on the road[]
There's a glitch that the players allow to place vehicles on the road, even if the game doesn't let you. On Reddit post how to place vehicles on the road.
Black Friday Promotion[]
To get all prizes (including a high-end premium item) from the Black Friday Promotion, the players must purchase donut packs that come with Gold Tokens with real money to make outright purchase. If the players bought donut packs that don't come with Gold Tokens after being purchased once each time, the personal prize doesn't count. It recommends emptying it out from Yearbook Mystery Box to increase chances before opening the Gold Mystery Boxes.
NOTE: Earned in game donuts may not count towards the personal prize.
