vishva.lol is a creative coding laboratory and playground for interactive web experiments, aesthetic productivity tools, and digital toys developed by Vishva Variya.

What kind of projects are on vishva.lol?

The site features a variety of experiments including an aesthetic Pomodoro timer, a startup pivot museum, a live flight tracker (Sky Spy), an AI model leaderboard (AI Battle), 3D character toys (Toodles), and engine sound simulators (Roar).

Is vishva.lol free to use?

Yes, all experiments and tools on vishva.lol are free to use and designed for browser-based interaction without requiring any downloads or signups.

Is this coin flip truly random?

Yes. We use cryptographically secure random numbers (Web Crypto getRandomValues) to determine the outcome, ensuring an unbiased heads or tails result every time.

Which coins are available?

You can flip US Dollars, Indian Rupees, Euros, British Pounds, Japanese Yen, Mexican Pesos, Chinese Yuan, Bitcoin, Ethereum, Dogecoin, Shiba Inu, Mario coins, Pokémon coins, and more.

Is the 3D coin physics real?

The coin uses real-time WebGL 3D rendering with a charged spin meter, but the heads or tails outcome is decided by a cryptographically unbiased random draw, not the simulated physics.

Is the coin flipper free?

Yes. The 3D coin flip is free, requires no signup, and runs entirely in your browser.

A 3D coin flipper for decisions, not wagers

A free, browser-based heads-or-tails simulator with realistic physics and a cryptographically unbiased outcome.

This is a decision-making toy. Press and hold to charge the flip, release to send a 3D coin spinning, and the page returns heads or tails. The outcome is decided by the browser's cryptographic random number generator, not the rendered physics, so every flip is statistically fair.

Not a gambling product. No money is staked, no prizes are awarded, no third party clears wagers. The coin exists purely for splitting bills, settling tabs, picking a restaurant, deciding who drives, breaking creative tie-ups, or any other small everyday call you would otherwise outsource to a real coin.

How the randomness works

Every flip calls crypto.getRandomValues() — the cryptographic random source built into modern browsers — to pick heads or tails with equal probability. The 3D animation is cosmetic; the result is locked the instant you release the button.

Because the source is the operating system's CSPRNG, the distribution over many flips converges to 50 / 50, well within the statistical limits expected of a fair coin.

Pick a coin

The garage ships with major world currencies (USD, EUR, GBP, INR, JPY, MXN, CNY), a handful of well-known crypto tokens (Bitcoin, Ethereum, Dogecoin, Shiba Inu), and a few pop-culture coins (Mario, Pokémon). They are visual variants only — every coin shares the same fair random draw under the hood.

Streaks and tally

A small counter at the edge of the screen tracks heads, tails, and current streak for the session. Refresh the tab to reset. Nothing is uploaded; results live only on your device.

Frequently asked questions

Is this gambling?: No. There is no stake, no payout, no leaderboard tied to money. It is a free decision-making toy.
How fair is the flip?: The browser's cryptographic random generator decides the outcome. Over many trials, results converge to 50% heads / 50% tails.
Can I install it offline?: Not yet. The coin flipper runs in any modern desktop or mobile browser, but does not currently ship as an installable PWA.
Why do I see crypto and pop-culture coins?: Variety. They are skins on the same fair coin. You can pick a coin that matches the decision or the mood; the math underneath does not change.
