[ Industry challenges ]

What a bug costs in games

The failures game studios bring to us most often. Players rarely report them; they just stop playing.

01

Lost progress after an update

A save that doesn’t migrate, or a level that resets, is the fastest route to a one-star review and an uninstall.

02

Purchases that don’t deliver

The store takes the money and the coins never arrive, or a restore fails on a new phone. Refund requests follow.

03

Crashes on the phones players own

A game that runs on flagship devices can stutter, overheat or crash on the mid-range Android phones most players have.

04

Balances and payouts that don’t add up

In real-money and fantasy games, a wrong entry fee, prize or withdrawal is a financial problem, not a bug.

05

Launch days and live events that fall over

Contest deadlines, new seasons and limited-time events bring the traffic spikes where downtime costs most.

06

Store, age and gambling rules

An App Store rejection, a missing age gate or a geolocation gap can delay a launch or put a licence at risk.

[ What we test ]

Testing mapped to the player journey

Each practice is pointed at a moment in the player’s life, from first launch to the hundredth purchase, and links to the full service.

Most critical

Gameplay, progression & saves

Rules, scoring, levels, rewards and saved progress played through end to end, including across updates, reinstalls and devices.

[ Test scenarios ]

The checklist behind every release

Pick an area to see the scenarios we run, and the client platform where they matter most.

[ Compliance & standards ]

Tested against the rules your game answers to

Stores, age rules and, for real-money games, gambling regulators all have a say. We test the controls and hand over evidence your team can use.

App Store · Google Play

Store review guidelines, purchase and subscription rules, loot-box odds disclosure and restore flows checked before you submit.

Age ratings · COPPA · GDPR-K

Age gates, parental consent, ad and data rules for younger players, and ratings that match what’s in the game.

Gambling regulation

Rules for real-money and casino play in the markets you’re licensed for. We aren’t an accredited test lab; we give your lab and compliance team evidence.

Responsible gaming · KYC · Geo

Deposit and time limits, self-exclusion, identity checks and location blocking tested against your rules.

[ Platforms, engines & tools ]

[ Case studies & results ]

Five live games, from casual to real money

A fantasy sports platform, a social casino, an online casino, a casual card game and a studio rewards project.

Real-money fantasy sports · North America

AmericanDream11

650+test cases across the contest and wallet lifecycle
180+defects found and verified before release
1,000concurrent players simulated before deadlines
3 monthsfrom first test to launch-ready

The challenge

Team building, contest entry, live scoring, wallet balances, refunds for cancelled matches and Zelle payouts all had to work across separate native Android and iOS apps, with traffic peaking in the minutes before every contest locked.

Our approach

  • Team rules, credit caps and edits after contest lock
  • Direct API calls that try to bypass app-side validation
  • Deposits, entry fees, refunds and Zelle withdrawals reconciled end to end
  • JMeter load at 1,000 concurrent players before deadlines
  • Android and iOS parity on BrowserStack real devices

Social casino · Android & iOS

What we test

  • Coin packs, offers and purchase restores
  • Daily bonuses, streaks and timed rewards
  • Reels, paylines and win animations
  • Performance on mid-range Android phones

Solitaire Pets Adventure

Casual players forgive nothing. A mis-scored move, a lost level or a tutorial that confuses them ends the session and often the install.

  • Level progression and pet unlocks
  • Saved progress across sessions
  • Tutorial and first-time experience

Venture-studio project · Superlayer

Trophy

Built by a studio that co-founds consumer and gaming products. Rewards and achievements only motivate players if they’re earned, shown and kept correctly.

What we test

  • Achievement and reward triggers
  • Player accounts, profiles and sign-in
  • Reward balances across devices
  • Launch-build regression
