CS2 Over/Under Betting Explained

An ‘Over/Under’ or ‘Total’ bet is pretty simple. A betting site sets a number for a specific aspect of an event, and you bet on whether the actual result will be over or under that number. The easiest way to explain over/under betting in CS2 terms is to use an example, so we’ve done that below.

We’ll use the commonly available ‘Total Rounds’ CS2 bet type to demonstrate precisely how over/under betting works. Let’s say your CS2 betting site sets an over/under total of 20.5 for the number of rounds played on a specific map in a match. You’ll need to determine how many rounds are likely to be played, then bet on ‘under’ or ‘over’ accordingly. At many betting sites, you can change the CS2 over/under target, but the odds you get will shift as you do so!

The form of both teams, their head-to-head record and the stakes of the event are just a few of the things that will affect an O/U total like ‘Total Rounds’. Some bookies may even have different lines. Before you place any CS2 over/under bet, you need to assess whether the odds you’re getting represent good value.

‘Total’ bets can often present substantial esports betting opportunities. For Example, if one CS2 team is heavily favoured to win, the ‘Total Rounds’ target is likely to be low, as chances are the underdog won’t win many rounds to push up the total. However, if you think a squad is by unestimated, a bet on the ‘Over’ could provide concrete value.

As we’ve already stated above, there are various CS2 over/under betting markets. Each bookmaker will offer a different number for each match, but the more prominent a match is, the more likely betting sites are to provide multiple ‘Total’ bets for it.

We’ll break down a few of the commonly available CS2 over/unders that top bookies will offer for the Counter-Strike sports matches they cover.

Total Maps

You’re betting on how many maps will be played in a best-of-three esports fixture. Picking ‘Over 2.5’ means you think the match will go to a third map. You can back the ‘Under’ if you believe a team is going to win 2-0.

CS2 Kills

Most sites provide users with multiple CS2 Kills betting options, using the over/under format. Betting sites will set a ‘Total Kills’ line for a team or even individual CS2 player, and you need to determine whether they’ll get more or fewer kills than the set target.

These ‘Kills’ totals may be for the entire match or a specific map. For example, you can place an ‘Over 17.5’ bet on a particular player on the first map. That means they have to get at least 18 kills solely on the first map for you to win. Keep in mind that the number of maps played, each player’s form, and many other factors can affect which side of the ‘Total’ wins.

Total Rounds

Highly similar to the ‘Total Maps’ over/under, but focuses on a single map. The bookie sets a target for the total number of rounds played, and you need to decide whether the actual total is more or less than this. Both the ‘Total Rounds’ line and the odds are affected by which team is favoured to win the match and by how much.

That’s just a taste of the CS2 over/under bets that exist. Platforms with a stronger focus on esports often offer multiple other forms of over/under betting that focus on aspects of Counter-Strike gameplay. Bets like ‘Total Rounds Won by Bomb Defusal’ being a prime example we always look out for.

These more esports-friendly betting sites also often provide multiple over/under lines for each market we’ve mentioned. This feature lets you move the ‘Total’ to where you want it. However, the more you move it away from the standard ‘Total’, the more your odds will shift.

CS2 Over/Under Betting Tips

Now you’re up to speed with the different forms of CS2 over/under betting, it’s time to start picking some winners. We’ll share our top CS2 over/under betting tips below to give you the intel you need to spot those potentially rewarding CS2 bets.

Research Is Key

Research is key to any successful bet, and that’s no different for CS2 over/unders. You must look at each team’s previous results and stats to determine whether the ‘Over’ or the ‘Under’ is a solid CS2 bet.

For example, if you plan on placing a ‘Total Maps’ bet, head to both teams’ match pages. Take a look at their latest matches and check whether they tend to go to a third map. You can even check their last few head-to-head clashes to see whether the score follows a pattern or trend.

Get The Best CS2 Odds Possible

You should always be on the lookout for the best odds possible. If you’re confident you’ve found a good over/under pick, having an account on multiple betting platforms allows you to shop around and get the best CS2 odds for it. The better odds you get, the more cash you’ll win!

If you’re super confident you’ve found a winner, you could add it into a multiple bet with other CS2 bets to get better odds. Many esports betting sites now have a ‘Bet Builder’ or ‘Same Game Parlay’, which allows you to combine your picks on a single CS2 match!

Avoid Tilting

Tilting is never good. Not in gaming or betting. Even the most accurate CS2 experts can lose a bet, but the key is not to chase those losses. Unresearched bets and emotional decisions never lead to anything positive.

Every time you bet on CS2, or anything really, consider the merits of each bet before you place it. Then, you can continue to bet making rational choices, instead of just throwing your gambling budget down the drain. Winners know when to stop.

The tips above could help you win more CS2 bets.

Responsible CS2 Gambling

Betting on CS2 should always be fun, so if it’s negatively affecting you or your life, just stop. You can use several methods to ensure you stay safe when betting online.

Take a few minutes to familiarise yourself with the responsible gambling tools at the online bookmaker you’re using. Every online bookmaker will have an option for ‘Responsible Gambling’ or something similar in the header, footer or site menu.

We recommend HLTV users take the Gamalyze self-assessment test. This test will recommend the tools that can help you stay in control of your spending. You can head to our Safer Gambling page for even more helpful articles.
