The UK’s advertising watchdog has spanked online lottery betting operator Lottoland for misrepresenting the size of its potential US lottery payouts.

On Wednesday, the Advertising Standards Authority (ASA) upheld a complaint filed against the Lottoland.co.uk website for its July 2017 promotion of a “PowerBall £169 million” jackpot. The complainant felt the ad was misleading due to the jackpot’s value being contingent on whether the prize was paid in a lump-sum or by installments.

Lottoland defended its promo, saying that the options for taking either a lump-sum payment or a 30-year annuity, as well as the difference in ultimate monetary value, were clearly specified in the site’s FAQ and T&C’s.

The ASA acknowledged that the FAQ did indicate that Lottoland replicated the official US lottery payout rules, including the 38% tax provision, the fact that the lump sum represented 60% of the total annuity payout, as well as the rule about splitting the potential payout should the official PowerBall prize be divvied up among multiple winners.
