N.D. Cent. Code § 53-06.1-10
The organization shall provide playing chips of various denominations to players although the organization may use a metal coin rather than a fifty-cent chip. The organization may set the minimum limit for the original wager at not more than three dollars on one active table. If there is more than one active table at a site, the organization may set a higher minimum wager on additional tables. The maximum limit per wager may be set by the organization at not more than twenty-five dollars. Wagers in increments of one dollar must be accepted between the posted minimum and the posted maximum limit. A player may not play more than two hands at the same time. Only the player actually playing a hand may place a wager on that hand. Each player plays the player's hand against the dealer's hand. Any requirement to pool tips is within the sole discretion of each organization. Except for a site that has twenty-one gross proceeds averaging less than ten thousand dollars per quarter, an organization may not conduct twenty-one at the site with wagers exceeding two dollars unless the organization has first installed video surveillance equipment as required by rules and the equipment is approved by the attorney general.
