Gocase.gg

A CS2 case-opening platform: players open cases with the odds shown up front, upgrade and trade up items and withdraw skins to Steam, while the team runs cases, payments and withdrawals from its own admin panel.

Context

Where they started

Gocase.gg is a standalone studio product built from scratch: Laravel 12 on Octane, a storefront on Blade and plain ES modules, and a separate admin app on Vue 3.

Case sites live on player trust, so the rule from day one was that the server decides every outcome and anyone can verify it. The odds of every item are visible before paying, and each opening can be rechecked on the provably fair page.

The platform works end to end on a closed stand and is getting ready for launch: missions and seasons, email sign‑in and a live drop feed over WebSocket are next. We will keep adding to this case as the work goes on.

Solution

What we did

Opening like in CS2

The roulette follows the CS2 scroll curve and plays the game’s sounds. Up to five cases open at once in parallel columns, with a fast mode and auto‑opening with profit and loss limits. The server decides the drop and charges the balance in one transaction, so nothing can be tweaked from the browser.

Fairness you can check

Provably fair on HMAC‑SHA256: the server seed hash is published before the opening, the player sets their own seed, and a dedicated page recalculates any opening. The odds of every item are listed on the case page before paying.

Upgrade, contracts, inventory

An upgrade with a chance wheel computed on the server, contracts that turn 3 to 10 items into one, and an inventory with filters, bulk selling and withdrawal.

Payments and withdrawals

An internal GoCoins currency with coin packages. Top‑ups by card, crypto and CS2 skins; skins are withdrawn to the player’s Steam through a marketplace, with request statuses and a manual check for large amounts.

Growth and SEO

30 levels, referral links, a daily free case and promo codes. Six languages with hreflang, structured data, a generated sitemap and per‑page SEO editing in the admin panel.

The team’s admin panel

A separate Vue 3 and shadcn‑vue app: dashboard and funnel, a case editor with odds, a simulator and version history, withdrawals, bonuses, players and SEO. Sign‑in goes through Cloudflare Zero Trust with two‑factor authentication.
