Luck

Fortune Teller

Luck is a statistic that affects many different aspects of the game, such as the drop rates of geodes and chance of getting treasure from Fishing. There are two kinds of luck: Daily Luck, which is determined by the game, and Luck Buffs gained from eating certain food.

Daily Luck

You can check your daily luck by right-clicking on the Television and selecting "Fortune Teller." The Fortune Teller will give an indication of the daily luck stat modifier.

Luck is not affected by viewing the Fortune Teller Television Program (i.e., the luck value is not neutral if the player does not view the program, the luck value remains constant regardless.) Daily Luck does not change if the day is restarted.

A 0.01 increase in daily luck generally means a random event is about 1% more likely to happen.

Daily Luck Effects

Daily luck affects the following:

• Amount of wood dropped from trees

• Chance to discover ladders while Mining.
• Quality and number of ores obtained from Panning.
• Chance of getting a second item (in addition to ore) from Panning.
• Geode drop chance from rocks.
  • (Luck does not increase the chance to receive rare gems and artifacts from geodes.)
• Drop chance of Duck Feather and Rabbit's Foot.
• Chance of getting items from Garbage Cans and the chance the item is not trash.
• Chance your spouse will be jealous after giving a gift to another marriage candidate.
• Chance of treasure appearing while Fishing.
  • Chance of getting Neptune's Glaive from Fishing Treasure Chests.
• Results of playing slots at the Casino.
• Amount of lightning during a storm (higher luck = more lightning).
• Chance to double the number of extra crops yielded at harvest, for crops that allow extra harvests (i.e., Coffee Bean, Potato, Tomato, Blueberry, Hot Pepper, Eggplant, Cranberry, and Strawberry).
• Chance to find treasure rooms in the Skull Cavern.
• Amount of gold and items lost when dying in The Mines or Skull Cavern.
• Chance of finding gem nodes and mystic stones in The Mines or Skull Cavern.

Luck Buffs

In addition to Daily Luck, Luck Buffs gained from eating food will temporarily affect the same aspects of the game as Daily Luck, with the exception of the drop chance of Duck Feather and Rabbit's Foot. A luck buff of +1 means a random event is roughly 1% more likely to happen. The following foods provide a temporary luck buff:

Special Charm

After reading Secret Note #20 and solving the puzzle depicted, the player is awarded with a Special Charm that permanently increases daily Luck by 0.025.

Mechanics

Most random events in the game are determined by generating a random double-precision number in the range 0 to 1 that is then compared to the event's chance of happening. For example, when panning for ore the base chance for finding iridium is 1%. This means iridium is only found if the random number is less than 0.01.

Daily Luck typically increases the critical threshold for an event without any change in magnitude: a 0.01 value of daily luck changes the iridium ore panning threshold from 0.01 to 0.02. On the other hand, buffed luck values are significantly rescaled before being applied, with large variability in scale factors. For ore-panning alone, scale factors include 0.001, 0.002, and 0.04 (when deciding the type of ore, whether there's an extra item, and deciding the type of extra item, respectively). For iridium ore specifically the scale factor is 0.001, so if a player has a 0.1 value of Daily Luck and a +1 Luck Buff, the threshold is 0.021 (2.1% chance).

However, the exact meaning of Daily Luck and Luck Buff is always context-dependent, because every event applies luck slightly differently.

History
