Some components are designed to offer small chances of catching a mouse regardless of the mouse’s strength. It is not uncommon for lucky traps to grant hunters the ability to catch mice that seem far too powerful for their trap.

Luck is a trap attribute that gives the player a chance of catching a mouse even if it would have normally gotten away. Aside from power, a trap's luck rating also provides a chance to catch a mouse purely from luck. It is not uncommon for lucky traps to catch mice that are far more powerful than the trap or even sometimes outside of its primary power type; although luck makes no difference when using a power type that is ineffective against a mouse. Luck does not affect the attraction of mice. Additionally, hunters who complete special offers or donate for SUPER|brie+ receive an additional 7 luck added to their trap's luck and a Golden Shield on their Hunter's Profile page for 30 days or more.

The actual mechanics of how the various trap attributes work to catch mice are a mystery and part of the fun of the game is figuring out what strategy works best against the mice you are interested in catching.

There have been various Events that offer increased Luck. There have been some Bonus Luck Weekend events where all hunters gain an extra 5 luck regardless of location. During the Great Winter Hunt 2013, it was possible to get an additional 6 luck during Tournaments by building the Snow Cannon and Ice Armoury, while at the Festive Snow Fort. During MouseHunt's Sixth Birthday in 2014, hunters that built the Sound System got +5 luck at the Dance Hall. The Valentine's weekend in 2015 offered +13 luck. Hunters could earn up to +16 luck during the Royal Challenge in September 2016.The Lunar New Year events in 2017-2019 offered +50 luck if the hunter achieved the maximum candle height.

Details of luck

Luck is nonlinear, so the more luck you have, the more effective it becomes. Hence 8 luck is more than twice as good as 4 luck.

The trap effectiveness meter ignores any contribution of luck to your catch rate. This means the trap effectiveness meter is a very poor indicator of your ability to actually catch a mouse.

Trap setups

The weapon with the highest luck is the Golem Guardian Trap with the Golem Guardian Physical Skin Module fully charged up, with 32 luck. The base with the highest luck is the Denture Base with Ful'mina's Charged Toothlet available in the hunter's inventory with 20 luck. Hunters can also activate a time-limited trap aura(s) for +5 luck, these include the A-MAZE-ing Aura from the Labyrinth Puzzle Box Event, Chrome Aura from opening a Chrome Treasure Chest, Slayer Aura from opening a Slayer Treasure Chest and Winter Aura from the [Great Winter Hunt]]. These auras will stack.

The charm with the highest luck is the Ultimate Luck Charm (20 luck), and variants such as Festive Ultimate Luck, Festive Ultimate Lucky Power Charm, Ultimate Lucky Power Charm, Ultimate Snowball Charm and [[Ultimate Spooky Charm] ; the Rift Ultimate Luck Charm and Rift Ultimate Lucky Power Charm are part of the Riftwalker Set for an additional 5 luck and the Riftstalker Set for an additonal 10 luck, but only when paired with lower luck Rift weapons.

The highest observed luck value in-game is 250 luck, in Furoma Rift however, this setup will not catch any mice due to the wrong Power Type.

Since luck is nonlinear, it is a good idea to pair high luck bases with high luck traps and high power bases with high power traps.
