Contract Mystling Guide
Probabilities, milestones, and the fund breakdown for unlocking the limited Mystling Fool.
Buy the fund — claim the Mystling Fool
Mission rewards + free package + free fund + paid fund stack to a median of 180 hearts — enough to claim the 180-heart Mystling Fool.
At a Glance
Heart Distribution Across the Recommended Run
Monte Carlo over 10,000 runs of 129 draws. The average alone hides the swing from rare crits — these percentiles show the realistic spread.
Cumulative Reward Track
Median draws to milestone: ~46 for 60 hearts, ~88 for 120 hearts.
Multiplier Roll Per Draw
Each draw rolls a critical multiplier. The result multiplies only the hearts banked toward milestones — the reward itself is not multiplied. Example: 1 draw (300 coin) + 5× crit → 5 hearts banked + 300 coin.
Per-Draw Reward Pool
Probability of each reward when you send a single heart gift. A critical proc does not multiply this reward itself.
Contract Mystling Fund (1499 Aurora)
A one-time fund that grants daily draws over 7 days. Days 4–7 increase the paid daily draws.
| Day | Free | Fund | Total |
|---|---|---|---|
| Day 1 | 1 | +6 | 7 |
| Day 2 | 1 | +6 | 7 |
| Day 3 | 1 | +6 | 7 |
| Day 4 | 1 | +8 | 9 |
| Day 5 | 1 | +8 | 9 |
| Day 6 | 1 | +8 | 9 |
| Day 7 | 1 | +8 | 9 |
Contract Mystling Event Guide
The Contract Mystling event is a limited event built around the limited mystling "Joker." You earn milestone rewards from cumulative hearts and secure Joker at the final milestone (120 hearts). Because Joker is a limited mystling that will not return for some time after the event ends, a full clear is strongly recommended even for free-to-play and light-spending players.
This page consolidates the single-draw reward distribution, the cumulative-heart milestones, and the 1499 Aurora fund composition into one view. The recommended route combines mission hearts, free packages, and both free and paid funds — this puts you on track to reach the 120-heart milestone reliably at the median outcome.

A critical multiplier triggers on draws at a fixed probability, which significantly widens the variance of cumulative hearts. Planning around the average alone risks missing the milestone in unlucky scenarios. The "Probability distribution simulation" on this page is the result of 10,000 simulated runs of the recommended route, so you can preview milestone-achievement rates across upper and lower scenarios.
The fund alone may fall slightly short of an average 120 hearts, so the key is to claim every daily free draw and every in-game heart reward. The most efficient flow is to log in daily for the free draw, claim all mission heart rewards, then top up with fund or package purchases for whatever is missing.
Frequently Asked Questions
QDo I really need to secure Joker?
Joker is a limited mystling and will not be obtainable again for some time after the event ends. The thinner your mystling roster, the more value securing Joker brings — so even free-to-play and light-spending players should follow the recommended route on this page and aim for a full clear.
QDo I have to buy the 1499 Aurora fund?
The recommended route assumes you buy the 1499 fund. Reaching the 120-heart milestone with free rewards alone is difficult. That said, if your spending budget is tight, daily free draws and mission hearts will still get you some of the milestones — make the call based on what your resources allow.
QIs the average heart count enough to plan around?
No — because the critical multiplier triggers probabilistically on each draw, cumulative hearts spread widely around the mean. In unlucky scenarios you may end up one milestone tier below the average. Check the upper-75% and lower-25% bands on this page's distribution simulation as well.
QWhere do I get mission hearts?
Hearts are awarded for clearing missions on the in-game event mission screen. Use the Event Missions page on this site to compare mission progress and currency requirements alongside other events.
