1Win Multiple Bet Bonus

A 1WIN Multiple Bet Bonus (called "Express Bonus" or Acca Boost) is one of the best ongoing sportsbook promotions worldwide – it automatically adds up to +15% extra winnings to any successful accumulator (multi/parlay/express) bet with 5+ legs.

No opt-in needed, no promo code required for the boost itself (just place a qualifying multi and win). The bonus is paid in real cash (no wagering requirements) on top of your normal payout.

Stick to 8–12 legs: risk/reward sweet spot (10–15% boost without insane variance)
Mix heavy favorites (1.30–1.50 odds) to hit the min odds easily
Use 1WIN's "Bet Builder" for same-match multis – they count as separate legs
Combine with their 500% welcome (use code VALUETIPS for max $2,800 bonus money)
