What Does RNG Mean in Gaming?
Short for “random number generator”: the randomness behind loot, critical hits, shop rolls and other chance-based outcomes.
What does RNG mean in games?
RNG stands for random number generator, the part of a game’s code that decides chance-based outcomes. Players use it to mean luck itself: “good RNG” is a lucky drop or crit, “bad RNG” is a run of bad luck. Loot drops, critical hits, card draws and shop offers all depend on RNG.
Where RNG shows up
| Game | What is random |
|---|---|
| Destiny 2 / WoW | Loot drops and weapon perks, which is why a god roll can take dozens of runs |
| Genshin Impact | Gacha wishes, softened by the pity system |
| Teamfight Tactics | The units offered in each shop when you reroll |
| Dota 2 / LoL | Critical strikes and other chance-based effects |
| CS2 / Valorant | Part of the bullet spread, on top of the fixed recoil pattern |
True random vs. pseudo-random
Pure randomness can produce long streaks, like five crits in a row or none in twenty hits, which feel unfair. Many games smooth it out. Dota 2, for example, uses a pseudo-random distribution for many chance-based effects: the chance starts lower and increases after each miss, so results stay close to the listed percentage. Gacha games do something similar with pity, guaranteeing a reward after enough attempts.
How to deal with RNG
- Judge decisions, not results. A good play can lose to bad luck; over many games, good decisions win.
- Reduce variance with consistent strategies, such as safer compositions in TFT or reliable loot sources.
- Know the odds. Shop odds, drop rates and pity counters turn “luck” into something you can plan around.
Example
A TFT player needs a third copy of a 4-cost unit and rolls 30 gold without finding it, then loses the round. Their friend says “bad RNG”. Looking back, they also contested the same unit as two other players, which made bad luck much more likely.
