US Patent 11893860 Proximity increased chances of win during special event

A first electronic gaming machine (“EGM”) includes a processor circuit and a memory coupled to the processor circuit. The memory includes machine-readable instructions that, when executed by the processor circuit, cause the EGM to perform operations. The operations include determining that a first event has been triggered on a second EGM. The second EGM can be separate from the first EGM. The operations can further include, responsive to determining that the first event has been triggered on the second EGM, adjusting a probability of triggering a second event on the first EGM.
