Catch a Monster Update June 2026 — Update 0.37

By Earnaldo Team • June 28, 2026 • 7 min read

Catch a Monster dropped Update 0.37 on June 26, 2026, and it's one of the bigger patches the game has seen this year. The headline additions are a brand-new island, a live Trader Event, and the Rexie Evolution, but the quieter dungeon rework is what long-term players are talking about. Here's the full breakdown of what changed and how to make the most of it.

What's New in Update 0.37

The most visible part of Update 0.37 is the new island. A fresh island gives you new ground to explore and new monsters to chase, and it's the natural first stop the moment you log in. Pair it with the new Pet Collection quest and you've got a clear early-game loop to grind right away.

Running alongside the island is a live Trader Event. Trader events in collection games like this one usually let you swap currency or materials for limited stock, so they reward players who show up while the event window is open. If you've been sitting on resources, this is the patch to spend them.

The standout unit this update is the Rexie Evolution. It's a new evolution path that the community has already singled out as one of the strongest options in the game right now. Evolutions like this reshape what a viable team looks like, so it's worth knowing the requirements before you invest your monsters elsewhere.

On the systems side, Update 0.37 delivered a full dungeon overhaul. The devs added better reward control, replay support so you can re-run dungeons you've already cleared, the ability to fight dungeon battles with your main team, and a round of Dungeon Shop adjustments. These four changes together make dungeons far more repeatable than they were before the patch.

Two smaller but welcome tweaks round out the update. Daily Quest rewards were increased, so your routine login grind now pays out more, and the Admin Abuse event was scheduled twice rather than once. That dual scheduling means players in different time zones both get a fair shot at the event instead of one region missing the window entirely.

How This Affects Gameplay

The dungeon rework is the change that touches your daily routine the most. Before this patch, dungeons were largely a one-and-done affair. With replay support, you can now grind a cleared dungeon for its rewards again, which turns dungeons into a steady farming loop instead of a one-time clear.

Being able to bring your main team into dungeon battles is a bigger deal than it sounds. It means you don't have to build and maintain a separate dungeon-specific squad, so the monsters you invest in for everything else carry over directly. Your strongest units, including a fresh Rexie Evolution, now pull double duty across dungeons and the rest of the game.

The reward control and Dungeon Shop changes work hand in hand with that. Tighter control over what dungeons drop lets the devs keep rewards meaningful as players replay them, and the shop adjustments shift what those rewards are worth spending on. Expect to revisit your dungeon strategy now that the payout math has changed.

As for the Rexie Evolution, its arrival matters because it raises the ceiling on team power right as dungeons became more central. A strong new evolution is exactly the kind of unit you want to anchor a main team that's now expected to clear dungeons on repeat. If you chase one thing this patch, this is it.

New Codes

No specific new codes were confirmed with Update 0.37 at launch. The patch focused on the new island, the Trader Event, the Rexie Evolution, and the dungeon overhaul rather than a fresh code drop, and we'd rather tell you that straight than list codes that don't work.

Codes in Catch a Monster do rotate in around major milestones and events, so it's worth checking back. We keep a verified, up-to-date list on our Catch a Monster codes page and refresh it the moment a new code is confirmed working, so bookmark that page rather than redeeming anything you can't verify.

Updated Tips and Strategies

The smart play this patch is to front-load the time-limited content. The Trader Event won't be open forever, and the early days of a new island are when fresh monsters feel the most rewarding to catch. Get those done while they're fresh, then settle into the new dungeon farming loop.

1. Head to the new island first and start the Pet Collection quest to build early momentum
2. Spend your saved currency and materials at the Trader Event before the window closes
3. Work toward the Rexie Evolution so your main team has a top-tier anchor unit
4. Re-run cleared dungeons with the new replay system to farm rewards on repeat
5. Bring your main team into dungeon battles instead of building a separate squad
6. Log in daily for the boosted Daily Quest rewards and catch the Admin Abuse event in your time zone

Don't sleep on the boosted Daily Quest rewards either. The increase means your routine login grind now compounds faster, which matters when you're saving toward the Rexie Evolution or stocking up for the next Trader Event. A few minutes of dailies a day adds up over a patch cycle.

The dual-scheduled Admin Abuse event is a small quality-of-life win you should actually use. Because it runs twice across different time zones, there's no excuse to miss it. Check both scheduled windows and join whichever lines up with when you're online, since live dev events tend to hand out the kind of bonuses you can't get from normal play.

Community Reaction

Reaction to Update 0.37 has centered on the Rexie Evolution. Players quickly framed it as a strong, OP-tier new evolution, and that hype landed right alongside the new island as the dual draw of the patch. When a single unit gets that kind of attention this fast, it usually shapes the meta for the weeks that follow.

The speed of the response says a lot too. Guide videos and patch-note breakdowns for Catch a Monster started appearing within a day or two of the June 26 release, with creators walking through the new island, the Trader Event, and how to actually reach the Rexie Evolution. That quick turnaround is a good sign the update gave players enough new content to dig into.

Among veteran players, the dungeon overhaul earned its own share of approval. The combination of replay support and main-team battles is the kind of behind-the-scenes change that doesn't make a flashy thumbnail but quietly improves the day-to-day grind, and the community noticed.
