The xPoints leaderboard currently includes players from around the world, so games and the number of spins can vary by region. UK tournaments have fewer spins because the auto-spin feature is not allowed for UKGC-licensed operators, keeping play shorter and simpler.
UK players do benefit from cash prizes in free tournaments. Plans are underway to separate the leaderboard by region, so you will soon only see UK players in the UK leaderboard. Rest assured, all cash prize tournaments are fair and competitive.
