Upgrader Simulator FAQ
The essentials: what the site is, how to play, where to get coins and why you can trust the results.
What is Upgrader Simulator?
A free online CS2 skin upgrade simulator: pick your items, a target and a chance — and spin. Just like a real upgrader, only with virtual coins and no money at risk.
Is it free?
Yes. Bonuses give you coins to start: 10,000 for joining the Telegram channel, 5,000 every day, promo codes and a free drop. Topping up is optional.
Can I withdraw skins or coins?
No. Coins and items exist only inside the simulator: they are never withdrawn to Steam or exchanged for money.
Is the site related to upgrader.pro?
No. upgrader.uk is an independent simulator, not affiliated with upgrader.pro, Valve or Steam.
How do I sign in?
With Steam, Telegram or Google — one click, no password.
How do I get free coins?
Every way is listed on Promo codes and bonuses: the promo code, Telegram, the daily bonus, your nickname, friends and the free drop.
How does an upgrade work?
Chance = stake price ÷ target price × 1.03, capped at 80%. The full table and a calculator are in upgrade tactics.
What are upgrade battles?
Several players put skins into one pot; each one's chance equals their share and the winner takes it all. Create or join a lobby on Battles.
Are the results fair?
Yes, every roll is provably fair (server seed, client seed, nonce) — see Provably fair.
What is streamer mode?
A paid feature that makes the site look exactly like the original upgrader — handy for streams and videos. Rent: 1 day — 299 ₽, 7 days — 990 ₽; forever — 5,000 ₽. A 2-minute demo is free.
How do I top up?
With a Visa, Mastercard or Mir card from 50 ₽, or with crypto via CryptoBot. Rate: 1 ₽ = 100 coins; the first top-up gets +50%.
Is there a mobile app?
The site works fully in a mobile browser and can be added to the home screen.
