Original cards had tiny insert arrows on cards from the Outpost Casino while cards from the Indigo Sky Casino had larger arrows. The Outpost website address on the Outpost cards was "TheOutpostCasino.com" vs "OutpostCasino.com" on the Indigo Sky Casino cards.

New found black GO Rewards card from the Outpost Casino in West Seneca, OK now has the larger insert arrows like on the Indigo Sky cards but the Outpost web address is still "TheOutpostCasino.com"
