Fons Rush: 2x Fons Event Guide

Event Overview

Fons Rush runs from June 8, 2026 at 05:00 server time to June 15, 2026 at 04:59 server time. During the event, spending City Stamina in eligible Hethereau Hobbies doubles the Fons you earn, up to the event cap of 700 City Stamina.

The basic math is simple: one City Stamina normally converts into 1,000 Fons, so a full 700-stamina week is usually worth 700,000 Fons. During Fons Rush, that same capped spend becomes 1.4 million Fons. Extra City Stamina refills do not raise the event cap, so plan around the natural 700 first.

Reach The 700 City Stamina Cap

If your weekly City Stamina cap is below 700, push your City Tycoon level before dumping stamina into the event. The video points to City Tycoon Level 23 as the breakpoint that raises the cap to 700.

Do this before the event window ends. Missing the cap means leaving doubled Fons behind, and refilling stamina afterward can cost Annulith without creating extra doubled-event capacity.

Fastest Spend: Owner’s Selection Cafe

The fastest active method is the Cafe Owner’s Selection mini-game. The suggested setup is Mint , Nanally , and Baicang with their Life Skills at least around level 3.

Each character has a clear job in the setup:

Character	Why They Help
Mint	Increases tips per combo, improving Cafe revenue while the streak climbs.
Nanally	Lets you hit customers with the hammer for a payout based on the current dish price.
Baicang	Keeps combos alive when customers lose patience or get hit by hammers.

Once the setup is active, the practical loop is to hammer customers quickly and let the combo/revenue continue climbing. The source video also mentions a possible Cafe strategy involving Daffodill and Lacrimosa , but that route was not explained in detail, so treat it as something to test separately rather than the core recommendation.

Lower-Effort Alternatives

Fishing is the easiest low-input way to burn City Stamina without needing a specific Cafe character setup. Go to a fishing spot, catch fish, then sell them through the shop to convert the stamina into Fons.

For an even more hands-off option, use Little Sparrow (Mahjong). Start a single-player game with three characters, enable the automation options on the left side of the screen, then check back after several minutes. This is slower than an optimized Cafe loop, but it is useful when you mainly want to spend the weekly stamina before the event ends.

City Deliveries are still worth considering if you are willing to play manually. They help level the Mailbox Anomaly Furniture, which improves the free weekly delivery income over time, so they trade speed for long-term account value.

Do Not Spend Event Stamina On Racing

The most important warning is buried in the event notice: Fons earned from races and challenges during Fons Rush are not doubled. Spend the 700 eligible City Stamina first, then do racing afterward.

If you race before spending the event-eligible stamina, you may need to refill City Stamina later to recover the missed doubled Fons. That can turn a free event bonus into an unnecessary Annulith cost.
