Product areas

One portal, separated workflows.

The public website now separates game creation, coding, documentation, and sandbox testing so people can get to the right task immediately.

/game

Game Studio

Install the game editor, copy game templates, activate `closedbit-game`, and test runtime-first examples.

/coding

Coding Studio

Install the compiler studio, copy command lines, activate `closedbit-coding`, and learn `.cbp` syntax.

/metrics

Measured Performance

See the current ClosedBit versus C++ snapshot, system specs, and why the measured rows are faster.

Sandbox and docs

Try shape, then compile locally.

The browser sandbox checks common `.cbp` mistakes and previews simple 256-bit results. The docs page is built for copy-and-paste learning.

Browser sandbox

Practice `.cbp`, load examples, check structure, and copy the result into Studio.

Open Sandbox

Copy-ready docs

Compiler commands, app templates, game templates, storage, UI, and license notes in copyable blocks.

Open Docs

License account

Login at the start, activate the product license, and keep entitlement visible.

Copy examples

Paste these into Studio.

Short, honest examples that match the current `.cbp` direction and avoid Python/C++ filler.

library CB-Storage

fn main() {
    u256 coins = 1_000_000 + 250_000
    CB-Storage.write_u256("save.cb", "coins", coins)
    println("saved coins")
    save coins
}
