Version 1.0 — Last updated on November 15, 2025
1.1 – The BIGGG Combo Boost is available to all players, both new and existing.
1.2 – Every sport and league counts toward this offer — no restrictions.
1.3 – You can qualify with both pre-match and live (in-play) combo bets.
1.4 – The boost is calculated instantly on your betslip so you always know the extra payout.
1.5 – Your Combo Boost amount is credited immediately once the combo bet is fully settled.
1.6 – No wagering requirements apply to Combo Boost winnings.
1.7 – You can place as many combo bets as you want each day. There’s no limit.
1.8 – Both pre-match and in-play combos qualify.
However, non-combinable markets — such as boosted odds or each-way bets — are excluded.
1.9 – Every leg must have minimum odds of 1.20 or higher. Combos using “banker” selections are not eligible.
1.10 – A minimum of 3 selections is required to receive a boost.
The more selections you add, the bigger the boost percentage.
1.11 – The promotion applies to all betting markets that can normally be combined in a combo.
1.12 – The maximum Combo Boost payout per betslip is €10,000.
1.13 – If any match in your combo is postponed or abandoned, the bet will settle with an adjusted boost based only on the remaining valid selections.
Example: if 1 of 7 legs is voided and the remaining 6 win, you’ll receive the boost for 6 legs (10%).
1.14 – If BIGGG detects misuse, bet-structuring, or attempts to guarantee profit, the Combo Boost may be removed, and bets may be settled without the boosted payout.
1.15 – The Combo Boost is intended for recreational use. BIGGG may restrict or remove access to the promotion at its discretion.
1.16 – BIGGG reserves the right to change, pause, or cancel the offer at any time. Changes won’t affect bets already placed.
1.17 – You may withdraw any withdrawable funds at any time unless BIGGG is required to restrict withdrawals for legal or regulatory reasons.
