Game Mechanics

This section defines the gameplay rules and economic mechanics currently implemented in the application.

Predictions​

  • You may place one prediction per tier per wallet.
  • A prediction consists of:
    • Selecting a number (0–9)
    • Choosing a conviction amount (your contribution to the pot)

Your conviction amount determines your proportional share of the pot if your number wins.

Winning Number Range​

The winning number is always in the range:

0–9 (10 possible outcomes)

Each epoch produces exactly one winning number derived from finalized on-chain data.

Probability​

Each prediction selects one number from the set {0–9}.

  • Probability of matching the winning number in a given epoch: 1 in 10
  • Probability of a payout event (non-rollover epoch): 8 in 10

Two outcomes always trigger a rollover (explained below).

Rollover Mechanics​

There are always two rollover numbers:

  • 0
  • The previous epoch’s winning number

If the winning number matches either of these values, the game rolls over into the next epoch.

When a rollover occurs:​

  • No winners are declared
  • No predictions are lost
  • The entire pot carries forward
  • All predictions remain active
  • Players may increase conviction
  • The taker fee decreases by 1% as a rollover incentive

Example​

If the previous winning number was 7, then the rollover numbers for the current epoch are:

  • 0
  • 7

If either value is selected as the winning number, the round rolls over.

Tiers​

The game currently operates in Tier 1.

Additional tiers may open over time with:

  • Higher conviction ranges
  • Larger pots
  • Different economic parameters

Each tier operates independently.

Pot & Taker Fee​

A taker fee is applied to each pot.

  • Gross pot = total conviction contributed by all players
  • Protocol fee = taker fee percentage
  • Net pot = gross pot − protocol fee

The net pot is distributed proportionally among winners.

Payout Model​

If your selected number matches the winning number (and it is not a rollover event), your payout share is:

(your conviction amount / total conviction on winning number) × net pot

This ensures proportional distribution among winners.

Change Tickets​

Change tickets are automatically awarded to a percentage of players who miss the winning number as a consolation mechanism.

A change ticket allows you to:

  • Override your existing prediction
  • Change your selected number
  • Do so before the cutoff time

Strategic Impact​

Switching to a number with fewer participants can significantly increase your potential share of the pot if that number wins.

Important:
A change ticket does not increase your probability of winning.
It only affects payout distribution if your chosen number wins.
