The studio

What we build

Ruby Fever is a set of casino-styled tables running in any current browser, with no plugin, no install and no account behind them. Three drums on Crimson Reels, twenty-one on Fever 21, a 37-pocket carousel, five-card draw, an over-and-under card run, a two-dice call table and a forty-number drum. The rules, the drawings and the engines are all ours.

Everything is staked in Rubies. Rubies keep score and manage nothing else: never withdrawn, never redeemed, never entered in a draw, never moved between players. That is the model in full, and it is not a phase we plan to grow out of.

What we will not build

• Real-money gambling of any description, including deposits and withdrawals
• Prizes, sweepstakes, raffles, giveaways or prize leaderboards
• Links to, adverts for, or sign-up funnels into sites that take real stakes
• Any suggestion that a player might earn, save or win something of value here
• Loss-chasing mechanics of any sort: no autoplay, no countdown deals, no notifications

How the lights stay on

Ruby packs, and nothing else. No advertising runs here, no analytics or advertising cookie is set, and nothing is sold or handed over for anybody's marketing. Buying stops at US$120 a month, and free Rubies arrive daily regardless, so carrying on never depends on a purchase.

The four rules we build by

1. Legible

   Rules and the whole paytable sit beside the felt, never behind a menu or a tooltip.

2. Honest draws

   Every outcome comes off the cryptographic generator inside your browser. The odds are never tuned, and a near miss is never staged.

3. Deliberate

   Each round starts with a press. Autoplay is absent by design rather than by omission.

4. Interruptible

   A break reminder arrives after 40 minutes at the table, and at each interval after that.
