Underdog Review 2026
Underdog is the platform Game of Skill reaches for first on CS2 and soccer pick’em. Here is what it does well, where it falls short, and the maths that decides whether any of it is worth playing.
Reviewed September 2026 by Game of SkillRead the break-even table before anything else. Every entry size on Underdog needs better than a coin flip on every leg, and the two pick asks for the most. That is the opposite of what most people assume.

CodeSKILLWhat each entry size actually asks of you.
| Entry | Payout | Break-even Per Leg |
|---|---|---|
| 2 picks | 3x | 57.7% |
| 3 picks | 6x | 55.0% |
| 4 picks | 10x | 56.2% |
| 5 picks | 20x | 54.9% |
| 6 picks | 40x | 54.1% |
Break-even is the hit rate you need on every single leg for the entry to come out flat over a long run, not a hit rate on entries.
Every entry size demands better than a coin flip on every leg, and the two pick at 3x asks for the most at 57.7 percent. A two pick feels safe. It is low variance, not a low bar.
Three picks at 6x is the friendliest short entry at 55.0 percent. Longer cards ask marginally less again, but every extra leg is another player you were not sure about. Depth is what lets you stay short: with thirty players on the board you can build three strong reads instead of stretching to six to chase the multiplier.
What shows up on the board when a tournament is running.
A major tournament day gives you 20 to 40 individual kill projections. BLAST, IEM, ESL Pro League and the Major are covered without gaps. Smaller regional events get thinner treatment and lesser known players there are often missing entirely. That is the honest limit.
Map count is the soft spot. A player in a series that goes the distance has a third more map time than one who gets swept, and the posted number does not always move with the shape of the series. That is the most reliable place to find a number worth taking, and exactly what CARNAGE and RANGE are for.
Strengths
More CS2 players posted per event than any US platform we track
Major CS2 and soccer calendars covered without gaps
App holds up during a live slate, which matters more than it sounds
Flex Play gives a floor when a fourth or fifth pick is a stretch
Weaknesses
Projections do not fully price map count, so you adjust yourself
Every entry size needs 54% or better per leg just to break even
Thin on lesser known players at smaller regional events
No exit once an entry is in, unlike a prediction market position

Pick your reads, then count them. Do not start from a multiplier and work backwards.
Match the entry size to the table above. If a leg cannot clear 55 percent on its own, it does not belong.
Pull the same player up elsewhere before you lock. 19.5 kills in one app and 21.5 in another are not the same pick.
Two different questions, two different edges, same slate.
Pick’em asks whether one player clears one number, and the entry locks once it is in. A prediction market prices who wins the series and stays tradeable until it settles. Those are separate edges and they do not turn up on the same nights.
A slate can carry a badly priced favourite and not one soft player number, or the exact reverse. Running both is coverage, not diversification. MARKET publishes our series fair values against live prices, CARNAGE and RANGE cover the player side.

Yes, with kill pick’em across BLAST, IEM, ESL Pro League and the Major. It posts more players per CS2 event than any other US platform we track. For how to read a kill projection see CARNAGE.
Per leg: 57.7% on a two pick, 55.0% on a three, 56.2% on a four, 54.9% on a five, 54.1% on a six. Anyone telling you a short entry is the safe option is describing variance, not the bar.
