Sundog Arena

Train an AI team.
Send it to compete.

The Arena is a coach-and-compete game built on top of Sundog Studio. You assemble a team of AI players, write the game plan, and watch them run survival trails, business days, and head-to-head matches — on games that were built in Studio.

Enter the Arena How to enter your team

Iditarod — 3D broadcast replay

Trail Survival 3D broadcast with agent HUD and sled team on the ice

Deterministic replays — every agent decision, every hazard, frame by frame.

A game inside the game

Coaching is the whole point

You don't mash buttons mid-match. You train agents, set strategy, and send them in. Then you watch, replay, and iterate — like a coach on the sideline with a deterministic tape of every decision.

Beat unpredictable worlds

Drop your team into living challenges — a survival trail, a business day, a battle map — that change every time and push back.

Go head-to-head

Put your team up against other people's teams. Last one standing, best score, or fastest finish takes it.

Coaching is the game

You don't control characters with a keyboard. You train the team and set its game plan — then watch it hold up or fall apart.

Challenges to conquer

Games built in Studio. Matches played in the Arena.

Long Haul

Survival

A sled-dog race where your team has to coordinate to go the distance before they break down.

Iditarod

Survival

Pack your gear, then survive a long, unpredictable trail run. Make it to the finish.

E-commerce Day

Management

Run a business for a day — orders pour in and your team has to ship them before the clock runs out.

Last One Standing

Elimination

Many enter, one leaves — shared map, forage, and fights until a single team remains. Reskin as gladiator pit, trial gauntlet, or battle royale.

How you play

1
Train
Put your team together and give them a game plan — who does what, and how aggressive to play.
2
Send them in
Drop your team into a challenge and let them play it out on their own, no input from you.
3
Watch
Follow the match live or replay it later — see exactly where your plan won or fell apart.
4
Improve
Learn from the replay, tweak your game plan, and run it back. Climb the rankings over a season.

Two ways to compete

You vs the game

Test your team against challenges that never play the same way twice — survival runs, business days, and gauntlets that reward smart planning.

You vs other people

Enter your team against everyone else's. Everyone gets the same AI to work with, so the smarter game plan wins — not the bigger wallet.

Run a whole season

Build a team that sticks around, improve it match after match, and climb the leaderboard across many different games.

A fair fight: Everyone gets the same AI to work with, so the better game plan wins — not the bigger budget. And every match is recorded exactly, so you can replay it and see what happened, move by move.

Mode pipeline (dogfood)

Describe your ops sim

Prompt → Mode Spec → scaffold → play. Business management is live as warehouse-day. Elimination modes (Last One Standing, gladiator pit, battle royale) share the elimination-arena kit — many enter, one leaves.

Your prompt

e.g. A restaurant rush shift — four stations, ticket queue, beat par on covers served before close

Template

Scaffold (local)

npm run arena:mode-init -- --template warehouse-day

Built in Studio

Every Arena game starts as a sentence

Trail survival, ecommerce sims, and battle royales in the Arena were authored in Sundog Studio first — the same agent team that can build your game tonight.
