MONOPOLY GO!: the guide to boosts and flash events — rolling your dice wisely on August 9, 2026

Sunday, August 9, 2026 is a double-switch day on MONOPOLY GO!: the solo event Bugs Bounty closes its milestones at 7:00 PM Paris time, a new tournament starts in that same minute, and the co-op event Looney Tunes Partners keeps running until Wednesday, August 12 at 10:00 PM. So everything you do with your dice this afternoon and tonight counts twice over.

Except the most profitable variable isn't the one people usually optimize for. Players collect free dice links, chase down missing stickers, then roll their dice at any hour — when in fact it's the boosts, those 5-to-60-minute micro-events that trigger on their own, that decide whether a ×10 roll nets pocket change or enough to finish off a landmark.

Here's how they actually work, what each one is worth, and the timing plan for the rest of the day on August 9, 2026.

What's still left to play today

An essential point before any table: Scopely does not publish any official boost schedule. The time slots below come from the daily tracking done by AppGamer and SuperCheats, who have been following the rotation for months and publish predicted windows. This is a strong probability, not a guarantee. These sources also work in US Eastern time: in summer, you need to add six hours to get Paris time.

On top of that, there are two fixed appointments that are perfectly stable: Quick Wins reset every day at 2:00 PM Paris time, and the switch between major events happens at 7:00 PM.

The rule almost nobody applies: window ≠ duration

A boost has two separate timers, and mixing them up is costly.

• The window — six hours in most cases — is the time frame during which the boost can trigger.
• The duration — 5, 10, 20, or 60 minutes depending on the boost — is the actual time you have once it's active.

The trigger is automatic: simply opening the game during the window is enough to start the countdown. The consequence is very concrete. If you open the app at 3:05 PM just to check a Partners notification, you've just triggered your Builder's Bash for the day, with zero cash in the bank. A boost burned this way doesn't come back.

The discipline to adopt fits in one sentence: during a promising boost window, only open the game when you're ready to play. The rest of the time, stay out.

Builder's Bash: the only real discount in the game

This is the most underrated boost and, by far, the most profitable one for a player who doesn't spend money. During Builder's Bash (called "Ruée des bâtisseurs" in Scopely's French-language help center), landmark upgrades go on sale — but not uniformly.

The discount applies from left to right across the current board's five landmarks, on a decreasing scale:

• 1st landmark: −50%
• 2nd landmark: −40%
• 3rd landmark: −30%
• 4th landmark: −20%
• 5th landmark: −10%

The rate doesn't change during the hour, no matter how many upgrades you buy. The resulting strategy is purely mechanical: you don't build anything between two Builder's Rush events. You stack up cash, wait for the window, and empty the bank on the leftmost landmark first. On a late-game board, where a single upgrade can cost billions, the gap between building during the boost and building the night before is simply double the board.

The benefit doesn't stop at cosmetics, either. Every upgrade increases your net worth and places a house on a randomly drawn property tile. Two valuable side effects: net worth milestones hand out free dice, and houses bring your color sets closer to "hotel" status, which is the requirement to access the wheel.

High Roller: the multiplier cap jumps

The High Roller is the exact opposite: very short, very costly, and only worth triggering if you know why.

Normally, your dice multiplier is capped — ×100 for the vast majority of accounts. During the High Roller, that cap is raised and can climb as high as ×1,000. Ten minutes, not one more.

The trap is obvious: at ×1,000, a handful of rolls can drain a stockpile built up over three days. The rule for survival is a matter of positioning — only raise the multiplier when your token is a few tiles away from its target. If tonight's tournament is scored on Railroads, move forward at ×10 until you're close to one, then switch to ×500 or ×1,000 for the decisive roll. If nothing lands after two or three attempts, drop back down immediately: a poorly played High Roller is the most efficient stockpile destroyer there is.

The other boosts, and what they're really worth

Scopely's French-language help center translates some of these names while the banner displayed in-game stays in English. Both labels are given here to avoid confusion.

Stacking boosts with what's running on August 9

A single boost on its own doesn't earn much. The real payoff comes from stacking, and August 9 offers three chances to do it.

Build, then spin the wheel

Completing a color set with hotels is the entry requirement for the wheel. Chaining a Builder's Rush — which places a house with every upgrade — followed by a Wheel Boost turns the board into a blue pack dispenser. If both windows overlap on the same day, the order isn't negotiable: build first, spin second.

Mega Heist and the 7:00 PM switch

MONOPOLY GO! tournaments almost always score on Railroads, via Shutdown or heist. Since the new tournament kicks off at 7:00 PM tonight, it's better to save your dice until then rather than spend them on the final milestones of Bugs Bounty, which closes at the exact same time. And if a Mega Heist lands during your tournament session, you score points and cash in on the same roll.

Partners: the countdown runs through the 12th

With Looney Tunes Partners active until Wednesday, August 12 at 10:00 PM, every Quick Win completed also earns partner event points. Sweeping through the daily tasks after their 2:00 PM reset remains the most profitable move of the day for a player who's almost out of dice — and it's free.

The end-of-day plan

Concretely, for this Sunday, August 9, 2026:

• Before 3:00 PM: don't build anything. Stack up cash, finish off the Quick Wins reset at 2:00 PM.
• 3:00 PM – 9:00 PM: open the game only once, with a full bank, to trigger the Builder's Rush and chain upgrades starting from the leftmost landmark.
• 7:00 PM: switchover. Bugs Bounty closes, the next tournament opens. Read the milestones before spending anything.
• 9:00 PM – 3:00 AM: the High Roller. Only trigger it if you have a stockpile to invest and a clear target; otherwise, let the window pass without opening the game.

One last habit, often overlooked yet decisive: when your dice are running dry, don't immediately claim the rewards from milestones already reached. Let the events run their course, then cash everything in at once. This way you rebuild a usable stockpile in one go, instead of frittering it away ten dice at a time. Over a season as long as Happy Harvest with Looney Tunes, which runs until September 23, 2026, this discipline alone changes the trajectory of an account.
