This guide breaks down not just what to do with vaults, but when and why—so your keys, dice, and time convert into the highest possible return, especially during a Monopoly Go Partners Event.
How vaults actually move your account forward
Dice liquidity: Vaults convert passive play (keys from dailies, milestones, and tournaments) into active play (dice you can deploy exactly when multipliers or milestone thresholds make them most valuable).
Album velocity: Mid/late-season vaults push missing stickers and wilds, accelerating album completion so you enter major events with a stronger economy.
Event compounding: Opening vaults while a solo/tournament/partners milestone bar is active means every payout nudges you toward more rewards.
Timing blueprint: Open later, stack more multipliers
Pre-event prep (24–48h before)
Hoard keys. Don’t touch vaults unless you need a single milestone to unlock a new feature.
Map your next 3 days: note when a solo event, a tournament, and (if announced) a partners event overlap.
Launch window (first 6–12h of an event)
Test the milestone curve: push to the first 3–4 thresholds using normal rolls, not vault openings. This reveals where the “good” rewards start (dice bundles, wilds, high-value packs).
Mid-cycle (the longest stretch)
Open vaults only when at least one of these applies:
You’re within one or two thresholds of a high-value milestone,
A 3×–5× board multiplier is live and you’re ready to roll immediately after,
You’re coordinating with partners to finish an attraction before a timer ends.
If a tournament is live, use vault payouts to finish mid-tier milestones (often the most efficient ROI).
Final push (last 6–12h)
Convert remaining keys into vaults to cross premium thresholds you’ve already “pre-paid” with effort.
If your team is stalled near the final attraction, time openings to cover dice gaps and seal the last reward tier. When schedules clash or teammates dip, outside help like monopoly go partner event boosting can bridge the last-mile deficit so your hoarded resources don’t go to waste.
Key farming you can control
Quick Wins & Dailies: Treat these as non-negotiable. The yield looks small daily, but it compounds.
Milestone chests: The cheapest keys in the game are the ones attached to rewards you would hit anyway.
Tournaments: Mid-table finishes are often more time-efficient than chasing rank 1; don’t over-commit dice just for placement cosmetics.
Album & Blitz windows: When Golden Blitz is active, trade to finish a page; finishing a page can nudge vault odds toward useful dupes or wilds later.
Practical math (lightweight, powerful)
EV of a key: Estimate “average dice per key” from your last 10–15 vaults. Track dice + sticker value (convert stickers to dice using your personal exchange rate: e.g., 1 wild = X dice saved).
Milestone bridging: If you need ~1,200 points to the next threshold and your vault EV is ~350 points of value, hold until two overlaps (solo + tournament) are active so the same openings bridge multiple bars.
Common pitfalls (and fixes)
Opening too early: You front-load rewards when you can’t multiply them. Fix: hoard until a clear overlap exists.
Ignoring tracker data: “Feel-based” decisions leak value. Fix: a 60-second spreadsheet—Columns: Date, Keys Used, Vault Tier, Dice Gained, Stickers/Wilds, Event Overlaps, Milestones Crossed.
Overchasing Golden Vaults: Lower tiers during the right overlap often beat Golden openings during no overlap.
A 7-day sample plan you can reuse
Mon–Tue: Key hoard; light tournament participation; fill sticker gaps.
Wed: If a solo event starts, open 30–40% of keys once the mid-tier milestones unlock bigger bundles.
Thu–Fri: Tournament overlap—open another 30% to clear mid/high thresholds; roll with 3×–5× to chain milestones.
Sat–Sun: Partners cycle—reserve ~30–40% of keys to cover dice gaps right before finishing attractions; convert late keys to vaults only if they push final thresholds.
