Axie Infinity Vibeathon live: AI game jam for 20,000 bAXS

Sky Mavis opened the Axie Infinity Vibeathon on September 1, 2026. The two-round online jam asks individual builders to ship a playable Axie Core game with AI coding tools and compete for a 20,000 bAXS community prize pool. Registration will close September 7. Strong builds can surface in the official gallery; up to eight finalists will advance to an October production round.

Background

Axie Infinity Origins is Sky Mavis's flagship battler on Ronin, the studio's gaming chain. Axie Core is the shared design bar Sky Mavis wants new Axie games to hit: playable loops that feel like Axie, not a generic browser toy with an Axie skin. bAXS is bonded AXS, the locked form of the franchise token used across Axie programs (see Sky Mavis's Bonded AXS guide⁠ (opens in new tab)).

The Vibeathon is the first public edition of that builder push. Sky Mavis frames it as a Lunacian-community pilot: test the tools, the two-round format, and the path from a hosted prototype to something that could later sit beside Origins as a standalone title or an approved ecosystem integration.

What happened

On September 1, 2026, Sky Mavis published The Axie Vibeathon is LIVE!⁠ (opens in new tab) on The Lunacian and opened registration at vibeathon.axieinfinity.ai⁠ (opens in new tab). The studio also announced the launch in the official Axie Discord⁠ (opens in new tab).

How to join

1. Register with a Sky Mavis Account on the Vibeathon portal (one entry per builder).
2. Build and host a playable game on hosting you control. The portal links to your build; it does not host or run the game for you.
3. Submit your best version with a title, one-sentence pitch, short and full descriptions, thumbnail, playable link, controls and first-play instructions, optional repository link, fallback demo video, which AI tools you used, and how the game fits Axie Core.
4. Finalize before the Round 1 deadline. The portal shows an on-screen receipt with the exact entry time. You may finalize a newer build before the cutoff; the latest valid entry counts.

Approved games can appear in the public gallery. Finalists are contacted directly after Round 1.

Prizes and pathways

Sky Mavis states that no winner, finalist, or recognized prototype is automatically entitled to a production pathway. Treat prize copy and any studio outreach as separate from a guaranteed ship slot.

Round 1 judging

Each valid entry passes eligibility and safety screening, then receives three independent judge scores. Up to eight finalists advance only if they meet approved quality, eligibility, and safety requirements.

Build support from day one

Sky Mavis points builders to:

• A Get Started guide from idea selection through playtest and submit
• The Builder Resource Kit (ready-to-use Axie assets, Origins Battle Kit, engine guides, Sky Mavis API setup, optional advanced tools)
• Vibeathon channels in the Axie Discord⁠ (opens in new tab) for questions

The blog notes a Three.js Axie Mixer beta but recommends ready-to-use 3D models for first prototypes when the mixer misbehaves.

You do not need to be a professional programmer to enter. The event assumes AI coding tools can help turn a clear concept into something playable; pick engines and helpers that match your idea.

Who it affects

Builders and hobbyist developers

If you want to prototype an Axie-facing game, this is the official window. Register before September 7 (portal cutoff 13:00 UTC), host your own build, and treat Round 1 (September 8–21) as the hard prototype deadline. Finalists will get USDC AI support and a full October production sprint.

Axie players

You are not the primary audience for registration, but you are the downstream audience for outcomes. Gallery entries and November demos are the earliest public look at what Axie Core might host next. Nothing in the rules promises that your favorite prototype becomes a live Ronin title.

Collectors and bAXS holders

Prizes pay from a 20,000 bAXS community pool, not a personal wallet top-up. bAXS is bonded AXS inside Axie loops; read live Vibeathon terms at signup for payout and eligibility before treating prize economics as settled.

If you still need to finish the separate Waypoint badge and bAXS migration before September 16, treat that wallet move as its own task. It does not register you for the Vibeathon and does not replace portal signup.

What to watch next

• Register at vibeathon.axieinfinity.ai⁠ (opens in new tab) before September 7 if you plan to build.
• Round 1 submissions will run September 8–21; finalize the newest valid build before that window closes.
• Watch the official gallery after approvals for playable links you can try without building.
• Follow The Lunacian⁠ (opens in new tab) and Axie Infinity on X⁠ (opens in new tab) for finalist names on September 29 and winner reveals on November 5.
• Read live Vibeathon terms for bAXS payout and eligibility before counting on prize economics.

Bottom line: Builders should register this week and ship a hosted Axie Core prototype by September 21. Players should treat the gallery and November demos as early signals, not a release calendar, until Sky Mavis names concrete integrations.
