What are CS2 Case Battles and how do they work?
CS2 Case Battles on DatDrop are multiplayer case openings played over several rounds. In each round, everyone opens the same case, but each player receives their own random drop.
- The conditions are visible before the start. The battle lists its cases, quantities, player count, modes and entry cost. Opening the same case again counts as another round.
- Rounds build a shared prize pool. It contains every participant’s drops, including those of players who will lose.
- The result is decided after the final round. The selected modes determine who wins and how the items are distributed.
How scoring works: a two-round example
2 players · no Jackpot or Terminal
Two rounds in Classic
65 > 60 — player 01 wins
Illustrative values explaining the rules, not current item prices.
Player 02 gets the higher value in round two: 20 versus 5. However, Classic counts both rounds: player 01 has 60 + 5 = 65, while player 02 has 40 + 20 = 60. Player 01 therefore wins the battle.
In the example above, 65 is the value of player 01’s own drops. The shared prize pool is 65 + 60 = 125. In a regular solo Classic battle, the winner receives the items from that entire pool. The losing player does not keep their regular drops; they receive a consolation prize.
With the same drops in Crazy, player 02 would win with the lower total. In Classic with Terminal, player 02 would also win because 20 beats 5 in the final round.
How much entry costs
In a regular battle, one player’s entry cost is the sum of all selected case prices, including repeated cases. For illustration, two cases priced at 3 and one at 4 give an entry cost of 3 + 3 + 4 = 10.
In a sponsored battle, the creator covers some or all of other players’ entry costs. Additional joining requirements may apply. The amount on the Join button shows what you would pay.
How the modes determine the winner
| Mode | How the winner is chosen |
|---|---|
| Classic | Without Jackpot or Terminal, the player with the highest total drop value across all rounds wins. |
| Crazy | Without Jackpot or Terminal, the player with the lowest total drop value across all rounds wins. |
| Jackpot | Drop values determine winning chances, then a random draw selects the winner. Higher values give a higher chance in Classic; lower values give a higher chance in Crazy. The favourite can still lose. |
| Terminal | Only final-round drops determine the winner or Jackpot chances. Classic, Crazy or Smoke rules still apply; earlier drops remain in the prize pool. |
| Smoke | At the end of the battle, it is revealed whether Classic or Crazy rules determine the result. Smoke can be combined with Jackpot and Terminal. |
One mode name does not describe every rule: Classic with Jackpot determines chances, while Classic with Terminal compares only the final round.
Team battles and prize sharing
- Team Battle. The rules apply to team totals. The entire prize pool is split equally among the winning team’s members. With Terminal, only final-round team totals are compared.
- Equality. All battle items are shared equally among all participants, regardless of their drops.
A Part Drop represents a share of a skin used to divide the prize equally. Team Battle and Equality are unavailable in sponsored battles.
What happens in a tie
If several players tie for first place, an additional random draw chooses one of them as the winner. A tie does not automatically split the prize equally.
Why the prize pool is not profit
To see whether you came out ahead, compare the value of the items you receive with what you paid to enter. Neither the shared pool nor your own drop total equals net profit. DatDrop item prices can differ from Steam prices.

The Fairness panel provides data for verifying drops and the draw. Read our explanation of Provably Fair for details.
Closing the page does not stop a battle that has started.
Previous losses, a case’s price or someone else’s large win do not guarantee your next battle’s result.
Case Battle simulator: what you can try
The Case Battle simulator lets you watch rounds and compare modes using a separate virtual balance. Its items cannot be withdrawn to Steam.
A virtual battle’s result does not predict a paid battle’s result.
