Power
The power rating of a trap determines the percentage rate of successfully trapping a mouse that is attracted to it, or the trap's effectiveness. Power refers to the strength of a mouse trap component, the overall strength of a trap and the component's power bonus. Weapons that are used to make a trap contribute to its power type. In Mouse Hunt, weapons have different power types, which have a varied effect on mice, depending on the mouse's weaknesses. The power bonuses of the base, weapons and charms used to make a trap add to the total power of the trap.
Trap Effectivess Levels
There are four levels of trap effectiveness: very effective, effective (normal), less effective and ineffective. Very effective traps are those that have a trap power bonus or luck bonus. Effective (normal) traps have no modifier added to the trap power or luck rating. Less effective traps have a penalty applied to the trap power or luck rating. Ineffective traps cannot catch a mouse at all. This is because different mice are immune to different power types. For example, a Bear Mouse is immune to a Forgotten Trap, which makes the trap ineffective at catching a mouse of that type.
Attraction Bonus
A mouse trap's power rating is not the main factor involved in catching a mouse; typically it is the type of bait cheese and its attraction bonus that determines whether or not you catch a mouse. A trap gains an attraction bonus depending on the type of base and weapon that is used to make it. Attraction bonuses are modifiers that raise the base attraction rate of the cheese you use to bait the trap from zero percent to 65 percent. This bonus determines how effective the trap is at attracting a mouse.
Luck Bonus
The luck bonus is determined by adding together the sum of weapon luck, base luck and charm luck of the trap. Luck increases a Mouse Hunter's chance of catching a mouse with the trap and is useful when a trap's overall power isn't strong enough (or effective enough) to catch a mouse.
Cheese Effect
The overall cheese effect adds to the attraction bonus of the trap. The cheese effect is determined by adding the weapon cheese effect with the base cheese effect. This sum is used to determine how fast the bait cheese will go stale when the trap fails to attract a mouse.
