The symbols usually consist of a traditional bell design set against a black background. Historically, this symbol signified winning when the machines weren’t automated. Symbols such as the horseshoe, heart, and diamond were also popular. Nowadays, fruit symbols are common.

The Bally Liberty Bell was an important milestone in the evolution of slot machines, introducing a number of exciting innovations and expanding the variety of symbols and sounds in slot machines.


The purpose of an audit is to verify whether the casino’s slot machines are functioning correctly. Slot machines have two independent data sources: the game meters and the physical count. The slot systems are designed to upload both types of data and allow auditors to compare metered bills with physically counted bills. They look for discrepancies in the two data sources and make necessary adjustments to correct them. Performing an audit should be done by an outside party with no affiliation with slot operations.


The European Commission has just adopted a proposal to relax airline slot rules. While current demand and forecasts show that air traffic will continue to recover, recent experience has shown that the current slots regime is not resilient to disruptions of this scale. The war in Ukraine, for example, shows how much disruptions can depress air traffic. To avoid further disruptions, the European Commission is proposing a ‘last resort’ option. Slot rules can still be changed, but the coalition is concerned that the change will limit competition and cause airlines to lose customers.
