A workshop, not a casino.

Stratosphynx runs free simulations of online casino games. Every board follows the real rules and the real odds of the format it simulates, and is played with practice points that have no cash value. There is no real money anywhere on this site, nothing to deposit, nothing to withdraw and nothing to win.

What this site is

Seventy boards in five families: roulette, online pokies, card games, scratch cards and bingo. Each board follows the published rules and the real odds of the format it simulates, and prints its grid, its limits and its pay table before you press anything.

Every family has a written guide, and every board has a guide of its own in which the probabilities are worked through with that board's numbers.

What this site is not

It is not a gambling service. There is no real money anywhere on this site, nothing to deposit, nothing to withdraw and nothing to win. Points are a scorekeeping number that lives in your own browser and cannot be bought, sold or exchanged for anything.

We run no advertising, no analytics and no mailing list, and we do not link to or promote any operator that takes real money.

How the boards are built

The outcome of every round is produced by a random number generator in your own browser. The figures in each guide are computed from the same configuration the board itself uses, so the page and the board cannot disagree.

Twelve boards in each family open with no account. Two ask for a free one, which is created and kept in your browser and is never sent to us.

Who runs it

The site is operated by Williwaw Studios OOD, a limited liability company incorporated in the Republic of Bulgaria. Write to us through the contact page.

For adults only

The site is for people aged 18 or over. If the simulations start taking more of your time than you intended, the Safer Play page lists free and confidential support lines.
