Monopoly GO! has swapped its usual city backdrop for Springfield during the Simpsons season, which runs from June 3 through July 29, 2026. There's plenty to chase, from themed albums to limited cosmetics, and players keeping an eye on the Monopoly Go Partners Event will probably recognise how quickly these short-run rewards can become the main target. The D'ohnut dice are one of those prizes: yellow dice covered in pink icing and sprinkles, made for anyone who wants a bit of Homer's favourite snack on every roll.

A Monorail With More Than One Stop

The big change is the Springfield Monorail Express. It takes the place of Tycoon Express and turns progress into a class-by-class climb. The screen isn't just a plain menu, either. You're sitting inside a monorail carriage with pink walls, blue booth seats, donuts on the counter, and the Nuclear Power Plant visible outside. It's a small detail, but it makes checking your upgrade bar feel less like admin. Express Coins come from normal board play and tournament activity, so there's no single magic button to press.

Monorail stage	What players should watch
Class III	Build enough Express Coin progress to trigger the promotion.
Class IV	Claim the D'ohnut dice from the reward display.
Class V	Prepare for a 190-point upgrade requirement and further rewards.

The Route to the D'ohnut Dice

The dice arrive when you move from Monopoly Class III into Class IV. Once the Class III bar is finished, an "Upgrade in progress!" moment plays out, followed by Mr. Monopoly's badge confirming the new rank. Then the reward case opens. That's when the frosted dice appear and can be added to your collection. If you're trying to get there without burning through rolls, a few habits tend to help.

• Check the Monorail bar before committing dice to a tournament.
• Use event play to earn Coins while picking up other milestone rewards.
• Don't ignore daily mini-games; small Coin gains can close an awkward gap.
• Claim Class IV as soon as it unlocks so the next target is visible.

Class V Needs a Proper Push

Class IV isn't the end of the track. Right after the dice are claimed, the Monorail points you towards Class V, where the next upgrade costs 190 points. That's a meaningful jump, so it's worth planning around tournaments and daily activities rather than rolling blindly. Higher classes can bring more Simpsons cosmetics and stronger returns from seasonal content, which gives active players a reason to keep going even after the dice are secured.

Make the Most of the Limited Season

July 29 will come around fast, especially if you're splitting attention between tournaments, albums, and board upgrades. Get the Class IV goal done first, then decide whether the Class V rewards fit your remaining rolls. Players also working on collections may find that buying Monopoly Go Stickers helps them finish album goals while they keep their main focus on Express Coins and the Monorail climb.
