The 2026 World Cup is just around the corner, and Bluff, a crypto sportsbook built by former Bet365 and Stake executives, is running a tournament campaign that rewards users for their sportsbook handle with instant casino rewards. From June 11 to July 19, 2026, Bluff will drop free spins on Hacksaw Gaming's Le King for every single World Cup wager settled.
The promotion works by crediting users with free spins after each match, based on the total qualifying stake placed on that specific game. The larger the stake, the bigger the reward. For example, users who bet between $50 and $249 will receive 50 free spins worth $0.10 per spin.
However, there are some structural limits to watch out for. Only single bets count toward match volume, and multi-bets are completely excluded from the calculations. Additionally, users must open the Le King slot by Hacksaw within 7 days of the match settlement to activate their spins.
