Random boxes appear and give bonuses when jumped into from the bottom. They appear every 30 to 120 seconds, and with the Mega Random Box upgrade it can be increased to 15 to 60 seconds and with the Roll The Dice upgrade it spawns every 13.6 to 54.5 seconds. Random boxes will not spawn while a menu is open on mobile in portrait mode.
Random Box Bonuses[edit | edit source]
These are the possible bonuses from activating a random box. Their durations can be modified by upgrades. Every 30 minutes, and after Day 2 of playing the game, a button appears to make the next random box a Silver Random Box. This causes the bonus from the box to be double what it normally is.

Random Box Chances[edit | edit source]
The chances of getting a given event are dependent on the Slayer's current map and the Bonuses that are unlocked. For example, if a map does not support Horde and you haven't purchased Mega Horde then the chances of picking the other bonuses are increased. Below is a table of chances, for maps with and without horde.
The chance of getting the Found Coins bonus can be decreased by 10% purchasing the Less Coins More Fun Divinity Upgrade. Note that this is not a flat 10% decrease from the table below, but a 10% lower chance that the bonus is picked in the spawning algorithm.
For a more accurate calculation of the chances, depending on the Slayer's map and unlocked bonuses and purchased divinities, use this calculator: https://idleslayer.com/calculator
