How to Fix Inconsistent Random Results in a Game

Inconsistent randomness is uncontrolled RNG. Using a seeded generator fixes it. Here is how.

How to fix it

1. Use a seeded RNG you control

Use your own random generator with an explicit seed rather than the default global one, so results are reproducible and consistent across platforms. Platform default RNGs can differ between systems.

2. Seed explicitly for reproducibility

For daily challenges, replays, or testing, seed the RNG with a known value so the same seed produces the same sequence. An unseeded generator cannot reproduce a run.

3. Separate random streams

Keep gameplay randomness (which affects simulation and must be deterministic) separate from cosmetic randomness, so adding a particle effect that consumes random numbers does not change gameplay outcomes.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
