In the Scratch Card widget, you can choose between two prize distribution modes: Probability-Based Mode and Fixed Cap Mode. Both modes determine how prizes are distributed to participants, but each operates in a different way.
This article explains the difference between the two modes and walks you through how to set them up.
1. Probability-Based Mode
Overview
In Probability-Based Mode, each prize has its own probability of being won. This mode is ideal when you don’t want to limit the total number of participants, but you want each scratch to have a certain chance of winning a prize.
For example, you can set a prize to have a 1/10 chance of being won, which means for every 10 participants, 1 might win the prize on average.
How It Works
- Each prize has an Odds/Probability setting, representing the chance for each scratch to win that prize.
- The system evaluates the chance to win independently for every participant, ensuring fair odds with each scratch.
- Prizes can be won multiple times depending on the probability you set.
Setting It Up
- In the Settings -> General section, select Probability-Based from the Prize Distribution Mode dropdown.
- For each prize (under Content -> Prizes), set the Probability/Odds by entering a number, which defines the odds of winning the prize (e.g., 1/1000 means a 1 in 1000 chance to win).
Example
If you have a 1/5 probability for a 10% discount and 1/10 for a free gift, the system will calculate the odds independently for each scratch.
2. Fixed Cap Mode
Overview
Fixed Cap Mode limits the total number of participants and how many times each prize can be won. This mode is useful when you want to ensure that only a fixed number of participants can win a prize.
For example, you can set a prize to be won by only 3 participants, and after that, no more participants will be able to win that prize.
How It Works
- You define a cap on the total number of participants.
- Each prize has a Max Wins value, which determines how many times the prize can be won.
- Once the participant cap or the max wins for a prize is reached, no more participants can win that prize.
Setting It Up
- In the Settings -> General section, select Fixed Cap from the Prize Distribution Mode dropdown.
- Set the Participants Cap to limit how many participants can join the scratch game.
- For each prize (under Content -> Prizes), enter the Max Wins value to define how many times that prize can be won.
Example
If you set a max of 3 wins for a 10% discount, once 3 participants have won, no more participants will be eligible for that prize.
Conclusion
Choosing between Probability-Based Mode and Fixed Cap Mode depends on how you want to distribute your prizes. If you want consistent odds for each participant, use Probability-Based Mode. If you want to control the exact number of winners and limit participation, go with Fixed Cap Mode.
By setting up the right mode, you can create an engaging and fair experience for all participants in your scratch card campaigns.
