Case Battles guide

The mechanic

Case battles compare drawn item values and distribute the pooled items under a winner rule. The fictional reference gives each player the same one-unit cost and independent half-chance draws of 0.5 or 1.3 units. Highest value wins the total drawn value; tied leaders share winning probability equally. No extra battle fee is charged. Winner probability alone cannot determine EV because the pooled prize varies with the joint draw.

The decision to notice

Inspect case EV, player count, tie rules, winner format, and platform fee before focusing on the head-to-head presentation.

03 / CHECK THE MODEL

Odds & mathematics

Probability describes frequency, gross return includes the original stake, and player net subtracts it. House edge is a long-run cost, not positive player expected value. None predicts a session.

Educational reference only, not operator odds or a claim about any independent lab. Operator limits, timing, availability and current fairness are not specified.
All payouts are gross (stake-inclusive). EV is player net per 1 unit staked; house edge = -EV. Decimals are rounded only for display.
Fictional independent two-value item draws, not a fixed cash pot. Complete joint enumeration accounts for variable prizes and uniform tie-breaking; each player has 90% reference RTP by symmetry and conservation of item value.
Popularity is unmeasured (legacy value 0). Difficulty is an editorial learning label; volatility describes the reference payout structure, not an independently measured operator rating.

Guide reference examples

These references are separate from the interactive model. A single row is not a complete distribution, particularly for pushes, multiple payouts, item values or fees. Missing expected net is not computed from an isolated row.

Guide examples, not current operator odds. Read the assumptions and payout basis for each row.
Scenario	Reference probability	Quoted payout & basis	Reference house edge	Expected player net / credit	Assumptions
2-player fictional case battle	50%	Variable pooled item value (1 to 2.6x gross if won)Gross return (includes stake)	10%	-0.1 units per 1 staked	Each of 2 players pays 1 unit and independently draws value 0.5 or 1.3, each with probability 1/2. Highest drawn value wins the sum of all drawn values; ties choose one tied winner uniformly. No extra battle fee. Symmetry gives each player win probability 1/2, but prize size varies with the joint draw: do not multiply that chance by a fixed prize. EV includes every joint draw and tie result. All payouts are gross (stake-inclusive). EV is player net per 1 unit staked; house edge = -EV. Decimals are rounded only for display.
3-player fictional case battle	33.33333333%	Variable pooled item value (1.5 to 3.9x gross if won)Gross return (includes stake)	10%	-0.1 units per 1 staked	Each of 3 players pays 1 unit and independently draws value 0.5 or 1.3, each with probability 1/2. Highest drawn value wins the sum of all drawn values; ties choose one tied winner uniformly. No extra battle fee. Symmetry gives each player win probability 1/3, but prize size varies with the joint draw: do not multiply that chance by a fixed prize. EV includes every joint draw and tie result. All payouts are gross (stake-inclusive). EV is player net per 1 unit staked; house edge = -EV. Decimals are rounded only for display.
4-player fictional case battle	25%	Variable pooled item value (2 to 5.2x gross if won)Gross return (includes stake)	10%	-0.1 units per 1 staked	Each of 4 players pays 1 unit and independently draws value 0.5 or 1.3, each with probability 1/2. Highest drawn value wins the sum of all drawn values; ties choose one tied winner uniformly. No extra battle fee. Symmetry gives each player win probability 1/4, but prize size varies with the joint draw: do not multiply that chance by a fixed prize. EV includes every joint draw and tie result. All payouts are gross (stake-inclusive). EV is player net per 1 unit staked; house edge = -EV. Decimals are rounded only for display.
