Understanding the Difference: Strict Probability Logic vs. Weighted Random Draw for Priiize Virtual Scratch-Off Cards

When setting up your Priiize Virtual Scratch-Off Game, one of the most important decisions you’ll make is determining how winners are selected.

We offer only Strict Probability Logic.

Here is the difference between the two logics for games:

Strict Probability Logic (Fixed Prize Inventory)
Weighted Random Draw Logic (Odds-Based Randomization)

Below is an easy-to-understand breakdown of the differences between the two, along with guidance on when to use each.

✅ What is Strict Probability Logic?

Strict Probability Logic means you’re working with a fixed inventory of prizes.

How it Works:

You define exactly how many winners there will be for each prize level (Example: 1 Grand Prize, 4 Second Prizes, 45 Third Prizes).
Priiize generates a pre-shuffled pool of outcomes that matches your total number of game plays (e.g., 1,000 scratch-offs).
Once all winning cards are revealed, no more of that prize tier will be awarded—even if plays remain.

Benefits:

✅ Guaranteed total number of winners
✅ Full control over prize budget
✅ Ideal for limited-time or event-based promotions
✅ Easier to comply with sweepstakes and promotional regulations
✅ Mimics the fairness model of printed scratch-off lottery tickets

Best For:

Campaigns with a fixed start and end date
Promotions with a strict prize budget
Regulatory environments where exact prize counts must be declared
Corporate and enterprise promotions where auditing and reporting matter

✅ What is Weighted Random Draw Logic?

Weighted Random Draw Logic is based on chance per play, not fixed inventory. Priiize does not use Weighted Random Draw Logic.

How it Works:

You assign a probability percentage (odds) to each prize tier.
Every time someone plays, the system calculates the result in real-time, based on the set odds.
The number of actual winners could be higher or lower than planned.

Example:

Grand Prize chance: 0.1% (about 1 in 1,000)
Second Prize chance: 0.4%
Third Prize chance: 4.5%

But actual results may vary based on a random draw.

Benefits:

✅ Easy setup for ongoing or evergreen campaigns
✅ Great for campaigns with flexible budgets
✅ No need to predefine the total number of game plays
✅ Ideal for casual, always-on engagement tools

Risks:

❌ No guarantee on exact prize fulfillment
❌ Possible budget overruns or too few winners
❌ Harder to predict outcomes
