The Indian Gaming Regulatory Act permits the use of electronic, computer, or other technologic aids in connection with the play of Class II games. National Indian Gaming Commission regulations at 25 C.F.R. part 547 establish minimum technical standards governing the use of such aids. Alternate technical standards from those required by part 547 may be implemented by tribes that have received approval from the NIGC Chair (25 C.F.R § 547.17(b)), provided that such alternate standards achieve a level of security and integrity sufficient to accomplish the purpose of the standards they are to replace.
