The Act establishes three classes of games with a differentregulatory scheme for each. Class II Bingo is defined as the game of chance commonlyknown as Bingo (whether or not electronic, computer, or other technological aids areused in connection therewith) and if played in the same location as the Bingo, pull tabs,punch board, tip jars, instant Bingo, and other games similar to Bingo. The Actspecifically excludes slot machines or electronic facsimiles of any game of chance fromthe definition of Class II games. Tribes retain their authority to conduct, license, andregulate Class II Bingo, as long as the state in which the Tribe is located, permits suchBingo for any purpose and the Tribal government adopts an ordinance approved by theCommission. Tribal governments are responsible for regulating Class II Bingo withCommission oversight.1.1.2 Class II Electronic Bingo Systems Defined. An Electronic Bingo System may becomprised of the following:a) Game Server;Chapter One – Overview – Class II Electronic Bingo Systems Page 4 of 56

Does not allow game play while the media containing the critical data, files,and programs is in a modifiable state.NOTE: If the program storage does not comply with any of the aboverequirements and is a Hard Disk, the media is permissible provided a writeprotecteddrive is used. SCSI Devices are preferred, as they provide a writeprotect jumper which can be sealed in place by the regulating body. Any othertype of drive will have the write line cut and verified in the field and any othermeans of write protection will be examined on a case-by-case basis.5.9 Critical RAM Requirements5.9.1 Comprehensive Memory Checks. Comprehensive checks of Critical Memoryshall be made during each Player Terminal restart (e.g., power-up cycle). The PlayerTerminal Control Program shall test for possible corruption of Critical Memory. Testmethodology shall detect 99.99 percent of all possible failures.5.9.2 Unrecoverable Critical Memory. An uncorrectable corruption of RAM shallresult in a RAM error. The RAM should not be cleared automatically, but shall require afull RAM clear (RAM Reset) performed by an authorized person.5.9.3 Function of RAM Reset. Following the initiation of a RAM reset procedure(utilizing a certified RAM Clear method), each bit in RAM must be set to the defaultstate. For games that allow for partial RAM clears, the methodology in doing so must beaccurate and the game must validate the un-cleared portions of RAM.5.10 Rules of PlayChapter Five - Player Terminal Requirements Page 48 of 56
