F032 — RTP Configuration

​
Business Rule

At installation time, the operator configures the target RTP for their deployment of Texas HedgeEm. This configuration controls:
  1. Target RTP — the percentage of total stakes returned to players over time
  2. Rounding Algorithm — whether and how odds are rounded to player-friendly values (see F033)
  3. Active Betting Stages — which of the four betting windows are enabled (see F014)
  4. Jackpot and Bonus Triggers — configuration of bonus round and jackpot trigger events (see F083, F084)
The RTP setting is an operator-level configuration — it is set once at deployment and applies uniformly to all game sessions for that operator. Players cannot alter it.

Source: Game Concept Document

“At install-time the operator sets the target RTP they desire Hedge’Em to run at.”
“The target RTP is set by the operator at installation time but the actual RTP can be influenced by other configuration parameters such as ‘Rounding Algorithms’ and player gameplay strategy.”
“Single vs Multistage: In its default configuration there is only one betting stage (POST-FLOP) but the operator can choose to enable other betting stages: ANTE-BET, PRE-FLOP, POST-FLOP, and TURN.”
“Configurable ‘Jackpot’ and ‘Bonus’ round trigger events.”

Configuration Parameters

​
Actual vs Target RTP

The operator sets a target RTP. Actual achieved RTP will differ from target due to:
  1. Rounding Algorithm (F033): rounding 3.71 → 3 reduces actual RTP below target
  2. Player strategy: players who consistently back the favourite achieve closer to target RTP; players who back outsiders achieve lower expected return per bet

​
Implementation Notes

Configuration is consumed during server-side game record generation. The JS and TS clients receive pre-generated records with the margin already baked in. Configuration is not a real-time client setting. For the standalone TS reference client, configuration will be handled via F042 (config screen) or build-time constants.
