User:Eiou/Sandbox/Score

Score is a numerical value that is affected by the player's actions over the course of a run. It has no effect on the game and is simply a measure of how successful a run is. Scores are calculated based on a combination of bonuses and penalties.

The current score can be seen during a run by holding the Map button or by enabling Extra HUD in options.

Leaderboard
At the end of a daily challenge, the player's score is placed onto an online leaderboard. The leaderboard can be sorted by time, score (globally), and score (friends-only).

Exploration Bonus
The exploration bonus is given for visiting and clearing rooms, and killing enemies. A bonus is also given for defeating Boss Rush and/or Hush.

Formula
$$ExplorationBonus = RoomBonuses + EnemyBonuses + 300 \times AngelStatuesFought$$

As clearly stated above, the Exploration bonus is merely a sum of all the room bonuses accumulated during the run, plus more points awarded for any Boss Challenge Room cleared or Angel statue killed.

Room Bonuses
Each room rewards points according to its type and size. 2x1 and 2x2 rooms are worth double the points stated. Rooms will default to 10 points for visiting and 40 for clearing if not stated otherwise.

Boss-Trap Rooms and Angel Statues
As you can see from the formula above, boss (not mob)-trap rooms and Angel Rooms will be used in the final tally of your score. In short, clearing a boss-trap room or killing an Angel statue will yield a lot more points than you previously thought, rendering Angel runs extremely more rewarding from a point standpoint.

Rush and Hush Bonuses
Doing Boss Rush will add 1,000 points; the same goes for Hush, for a total of 2,000 more points.

Enemy Bonus
Killing enemies will also add up to your exploration bonus - roughly 10 points for each killed enemy. The exact formula is:

$$\lceil EnemiesInTheRoom ^ {0.2} \times 5 \rceil$$

So, a room with just 1 enemy is worth 5 points; 2 enemies means 6 points each; 5 enemies 7 points each; 10 enemies 8 points each; 20 enemies 10 points each; 100 enemies 13 points each. Multiple enemy waves in Challenge Rooms and Boss Rush don't yield points, same goes for monsters' spawns (spiders, flies, silkworms, etc).
