CS2 Bombsite Randomizer

When the team has no real read on the CT side, picking a bombsite "by feel" tends to drift to the same side every time, this randomizer fixes that with a genuine A/B draw, an adjustable weight and a guard that avoids repeating the same site 3 times in a row.

How the bombsite draw works

The default weight is 50/50: every round has exactly the same chance of landing Site A or Site B. If the team notices the CT side over-favoring one lane across recent rounds, the weight can be tilted, say 60% toward Site A and 40% toward Site B, and the draw uses the browser's cryptographic random number generator (Web Crypto) to honor that proportion across many draws, not just in a single result.
The "avoid repeating 3x in a row" guard keeps track of your recent draw history, and whenever the natural result would create a 3rd consecutive pick of the same site, it re-rolls to the other side instead, without it, even an honest 50/50 draw can produce long streaks by pure chance, which makes the team predictable. The map selector (Dust2, Mirage, Inferno, Anubis, Ancient, Nuke and Overpass, the Active Duty pool as of July 2026) is just a label: all 7 of those maps have exactly 2 bombsites, so the draw logic never changes between them.

Examples

Default 50/50 draw

Input: peso 50% A / 50% B, sem mapa selecionado
Expected output: Site B

Each draw is independent and uses Web Crypto for real randomness.

Adjusted weight + guard on

Input: peso 60% A / 40% B, histórico A, A
Expected output: Site B (ajustado)

The natural result would be A again (3rd in a row), so the guard forces B even with the weight favoring A.

Full tool FAQ

Does this tool give an unfair competitive advantage?

No. It's a randomizer for removing decision bias, not a live read of the match, it never accesses the game, the server or replay data, and has no advantage mechanic of any kind. Either team, yours or the opponent's, could use the same kind of randomizer to decide bombsite, CT rotation or roles just as fairly.

Why avoid repeating the same bombsite 3 times in a row?

What exactly does the CT Default/Rotate tab do?

Is this tool affiliated with Valve or Counter-Strike 2?

Are player names or draws saved to a server anywhere?

Why is it always just A or B, even when I change the selected map?

Frequently asked questions

Does the draw's weight change its logic depending on the map?

No. The selected map is just a label shown alongside the result, the draw always chooses between A and B with the configured weight, regardless of which of the 7 Active Duty maps is marked.

Is this draw really random, or can it be 'gamed'?

The draw runs entirely in your browser using Web Crypto (falling back to Math.random if that API isn't available), there is no way to predict or manipulate the result from the interface, and no data is ever sent to a server.

Can I use this randomizer on both sides, CT and T?

Yes. The bombsite draw decides which site the T-side should commit to; the CT side can use this same randomizer's CT Default/Rotate tab to just as fairly decide who holds and who rotates.
