Vivarium — Browser Game

Collect. Battle.
Earn real money.

Vivarium is a browser-based creature battling game where everything has real value. Collect creatures, train them up, battle in ELO-ranked arenas, join a guild, trade on a live marketplace, and cash out when you’re ready. No app store. No download. No ads. No tracking. Like everything J&G Studios builds — we don’t sell your data. Just play.

The Game

Not a gacha. Not pay-to-win.

Every creature in Vivarium is earned through gameplay. There are no loot boxes. No premium currency. No $20 skin packs. No ads between rounds. No analytics tracking what you click. J&G Studios doesn’t do that on any platform — not this one, not any of them. You play, you earn, you trade, and if you want to cash out — you can. The economy is real because the money is real.

Collect & Train

Earn creatures through play, train them up by winning matches, and outfit them with cosmetics from the shop. Each creature has its own stats, shape, and history — build a collection that’s yours.

No gacha, no loot boxes

Battle & Rank

ELO-ranked arena battles. Pick your team, read your opponent, and outplay them. Win, climb. Lose, learn. Every win earns Bubbles — the in-game currency you can later cash out.

Competitive ranked PvP

Trade & Earn

Live marketplace where players set their own prices. Buy low, sell high. Bubbles are real money: deposits and cash-outs run through Stripe, with the rules spelled out in the Terms.

Real economy — real payouts

Guilds

Form a guild, donate to its treasury, and declare wars on rival guilds. The roster is small today — come now and you’re the founding members.
