US Patent 10456686 Methods and systems for adaptive tuning of game events

A system, a machine-readable storage medium storing instructions, and a computer-implemented method are described herein for a System Tuner for defining an in-game event requiring accumulation of a pre-defined set of virtual objects in a virtual game (or online game) prior to termination of the in-game event. The System Tuner determines a head-start subset from the pre-defined set of virtual objects for a target player account based on a difference between a reference player skill level for the virtual game and a player skill level of the target player account. The System Tuner determines, based on the player skill level of the target player account and a pre-defined duration of the in-game event, a drop rate for virtual objects remaining in the pre-defined set of virtual objects. The System Tuner sends the head-start subset and the drop rate to a client device associated with the target player account.
