Random Number Generation, or RNG, is a highly debated topic in almost every competitive video game genre.
However, it still exists in subtle ways that can completely alter the outcome of a very close match.

Initial Deck Shuffling
If your opponent rushes the bridge and all your cheap defensive counters are at the bottom of your deck, you lose the tower.
Professional players build their decks specifically to minimize the chances of a truly unplayable starting hand.
- Make the best play available with what you have.
- Track the opponent's rotation after the first cycle.
- It prevents matches from feeling perfectly scripted.
Unit Targeting and Pathfinding
While developers strive to make AI as predictable as possible, the physics engine can occasionally create chaotic results.
Leaving a slight margin for error in your defensive placements is the best way to handle AI unpredictability.
| Battler Category | Randomness Impact |
|---|---|
| Auto-Battlers | Luck is the primary factor in individual matches |
| Standard Tower Rush | Very Low - Only the starting hand is randomized |
The Mental Game
The most important skill regarding RNG is learning how to control your emotions when luck inevitably turns against you.
If you are stuck in a lower arena, it is because of your fundamental mechanics, not the random number generator.
