# Racing Battle

### Core Gameplay

Your NANO will run against 7 other NANOs in a straight line. It will automatically run as fast as it can. The first NANO to cross the finish line wins, but the first few places get points for the leaderboard.

## Speed and Stamina

Your NANO has a Speed and a Stamina trait that play a role in the game.

### Speed

The higher your NANO's speed value, the higher its base running speed. Your NANO's base running speed is not constant, though, but it (slightly) fluctuates randomly around its base speed. This is why two different NANOs with the exact same speed value won't be neck-on-neck all the time.

Speed is also influenced by other things like speed-ups, item effects or attacks.

The maximum achievable speed is capped at 150, so stacking speed-ups incorrectly might lose you some optimal strategy.

### Stamina

Stamina is the amount of time that your NANO can "boost". When boosting (usually by pressing the W key), your NANO reaches the maximum speed and holds it as long as its stamina is not used up yet.

Stamina doesn't refill by itself and only refills by using a Stamina Potion.

The maximum possible stamina charge is 100.

## Power Gems

Your NANOs have power gems that they can use for powerful attacks that help you win the race. You can learn more about the different power gems here:

The power gems have these effects in Rumble Race:

* Ruby:
  * Attacks another NANO for -30 speed for 3 seconds
* Sapphire:
  * Attacks another NANO for -35 speed for 3 seconds
* Onyx:
  * Attacks another NANO for -35 speed for 5 seconds
* Diamond:
  * Attacks another NANO for -40 speed for 5 seconds
* Cryptonite:
  * Gives your NANO +30 speed for 3 seconds
* Moonstone:
  * Gives your NANO +35 speed for 3 seconds
* Ethernite:
  * Gives your NANO +40 speed for 3 seconds
* HEROstone:
  * Gives your NANO +45 speed for 4 seconds

## Items

Along the track there are item boxes. If you don't already have an item, running through an item box will give your NANO a random item.

The further back you are, the better the items tend to get so that games can turn on their head until the very last second.
