Rush Street Interactive (RSI) has opened up the PropPacks betting tool at its BetRivers brand for baseball wagering.

The game links betting with the pastime of collecting sports cards. Players who bet US$10 or more on qualifying same-game parlays (SGPs) for MLB games will randomly receive up to three digital PropPacks player cards per game.

Each card features a player from one or both teams as well as Hits and Strikeouts milestones for those players. If those targets are met, bettors can win prizes based on the difficulty of the achievement.

Bronze, Silver and Gold – the rarest of the three tiers – are available to collect.

The tool is already live at BetRivers for basketball betting on the NBA.

“PropPacks give MLB fans another reason to get in on the action by adding surprise rewards to their same-game parlay bets, creating more ways to win with no added cost,” said RSI CEO Richard Schwartz.

“It’s all part of our mission to put players first by providing more value and innovation across every major sports season.”

RSI said it plans to add other PropPacks-linked baseball promotions throughout the season.

“We’re excited to keep building on the success of NBA PropPacks and expand this fun format across more leagues and seasons,” Schwartz added.
