Make NBA Picks on Cavs vs. Knicks with Underdog Promo Code TOPACTION
The Underdog promo code TOPACTION fits well for Cavs vs. Knicks because Game 1 offers plenty of angles across player projections and single-game DFS builds. Instead of committing too much cash right away, new users can play $5 and unlock $50 in Bonus Entries to create more lineups inside the fantasy app.
That extra entry volume is useful in a standalone national window like Cavs vs. Knicks at 8 p.m. ET on ESPN. Late injury updates, starting lineup news, and matchup adjustments can all shift player projections quickly, especially in Game 1 of a conference finals series. If you want more flexibility to build around Jalen Brunson, Donovan Mitchell, James Harden, or Cleveland’s frontcourt, the Underdog bonus code TOPACTION gives you more room to test multiple lineup constructions.
This offer works especially well for new users who want to start small, single-game players looking for extra build options, and conservative DFS users who prefer not to increase their initial out-of-pocket spend. The value is simple: play $5, get $50 in fantasy bonus entries, and use those extra entries on additional Cavs vs. Knicks picks.

How NBA DFS Picks Work for Cavs vs. Knicks
Here’s how I’d use the Underdog promo code TOPACTION on Cavs vs. Knicks Game 1 on Tuesday, May 19, 2026. If I enter a $5 pick’em contest on Cavs vs. Knicks, I begin by signing up and entering TOPACTION. That $5 entry qualifies for the “Play $5, Get $50 in Fantasy Bonus Entries” offer, so once it posts, Underdog credits my account with $50 in bonus entries.
Now let’s break down the value. If my $5 entry returns 2x based on the contest payout structure, I receive $10 back total, including stake. If it does not cash, I lose the $5 entry fee, but I still unlock $50 in fantasy bonus entries after the qualifying play posts. From there, I treat those bonus entries as a separate bucket from cash entries and use them to build more Cavs vs. Knicks cards instead of putting the entire bonus amount on one read.
- One-shot approach: Use 1x $50 Bonus Entry on one strong Cavs vs. Knicks build if I have a high-conviction card.
- Spread-out approach: Use 5x $10 Bonus Entries across different Cavs vs. Knicks combinations to cover more game scripts.
- More reps: Use 10x $5 Bonus Entries to rotate around player projections if late news changes the board.
- Mixed plan: Use a $10 cash entry, then split $40 in Bonus Entries into 4x $10 lineups so cash and bonus results stay easy to track.
