A separate draft has updated Regulation No. 903-A/2015, which governs online fixed-odds sports betting. The revision formally brings into law features that some licensed operators were already offering. Included in the most significant is the bet builder, which lets players combine related predictions within a single match or across numerous events.
The regulation also specifies how to calculate odds and determine winnings. The regulation introduces cash-out as an optional tool. It allows bettors to settle part of a wager before the final outcome, though at a reduced return.
The rules further explain when to void bets and state that odds become binding as soon as the operator accepts a bet. For multiple, combined, or personalized bets, the operator will settle any voided selection at odds of 1.00.
Adding mechanics that have already become standard in other European markets the SRIJ has also cleared the way for new slot features.
The amendment to Regulation No. 828/2015 introduces buy bonus and bet boost options. Both features aim to expand gameplay while keeping strict limits in place.
