DraftKings offers new users $100 in bonus bets after their first $5 wager on Tuesday's NBA and NHL playoff action. The promotion coincides with crucial conference finals matchups featuring both a No. 1 seed on the brink of elimination and a pivotal Game 5 showdown.

The Golden Knights aim to complete their sweep of the Avalanche, who entered the playoffs with the NHL's best record. Vegas rallied from a 3-0 first-period deficit to win Game 3 5-3, scoring the final five goals. Meanwhile, the Spurs-Thunder series sits tied 2-2, with Oklahoma City favored by 4.5 points despite San Antonio's defensive adjustments limiting Shai Gilgeous-Alexander to 24.8 points per game this series, well below his MVP-season average of 31.1.

Milwaukee turns to starter Kyle Harrison (1.77 ERA) against St. Louis, with the Brewers opening a 2.5-game lead in the NL Central after Monday's 5-1 victory. The SportsLine Projection Model backs all three favorites, projecting Milwaukee wins in 74% of simulations. Tuesday's slate presents clear value for bettors looking to capitalize on the promotional offer.

SportsLine's model projects the Under in Spurs-Thunder to hit in 59% of simulations, while favoring Vegas to close out the sweep in 53% of scenarios. Combining these picks into a parlay would yield $491 on a $100 stake, making Tuesday's promotional window particularly attractive for new DraftKings accounts.
