Intro

Add excitement to your customer experience with the Slot Machine campaign. This gamified feature lets customers try their luck—if all three slots align, they win a prize! From discounts and free products to bonus points, the rewards keep them coming back.

Creation Experience

How to Set Up	Open Gameball Click Add Reward Campaign Select the Slot Machine template Edit the campaign's setup Click Set Live
Trigger	Machine Banner on Widget: A banner will display on your widget’s homepage. When customers click the banner, they’ll be taken to the game screen where they can roll the machine. Deep Link: Use the `#gameball-slot` deep link to trigger the slot machine campaign from a custom banner or button on your website or app. Learn more.
Repeatability	By default, customers can roll the machine once per day. All Games campaigns support only the Limit per day/week/etc. Learn more.
More Setup	This template uses the standard reward campaign setup. See the Generic Setup Guide for details.

Rewards Setup

Types	Choose from any of the reward types supported by Gameball. Learn more. Min & Max Rewards Count: The minimum number of rewards allowed is 2 The maximum number of rewards allowed is 8
Probability	Enter a numerical value (e.g., 2, 3, 4) to represent the probability of a customer receiving this reward. This means that every spin is completely independent of the previous ones, and the chance of landing on a specific reward is always the same, no matter how many times you've spun the machine. The probability input can accept a value of 0, meaning the reward will not be available. Probabilities are calculated based on the sum of all assigned probabilities across the rewards. Important: Please note that while each reward has a set probability, it doesn’t guarantee that all rewards will be won equally over time. Some rewards might appear more often, while others might be less frequent. It’s all part of the random nature of the game! Example: Reward #1: Probability 1 Reward #2: Probability 1 Reward #3: Probability 1 After 100 trials, you might see results like this: Reward #1: 27 times Reward #2: 36 times Reward #3: 37 times In another set of 100 trials: Reward #1: 28 times Reward #2: 49 times Reward #3: 23 times
Reward Limits	The maximum number of times a specific reward can be claimed by all customers throughout the campaign. Optional Feature: You can choose to add a reward limit when configuring the campaign. Tracking Wins: Gameball will track how many times each reward has been won. After the limit is reached, the reward will still appear on the machine but will no longer be winnable. Reward Limit Adjustment: If you adjust the reward limit while the campaign is running: Increase the Limit: If the new limit is higher, customers can win the reward again. Decrease the Limit: If the new limit is lower, the system will prevent the reward from being won if the initial limit was already reached. Example: Reward 1: Probability 1, Limit: 1 Reward 2: Probability 1, No Limit Reward 3: Probability 1, No Limit After 10 trials, the results might look like this: Reward 1: 1 win (limit reached) Reward 2: 5 wins Reward 3: 4 wins Notes: If all rewards have limits and they are reached, customers will see a "No rewards available at the moment" message.

Customization:

Design & Content

You can fully customize each stage of the campaign through dedicated tabs representing the different screens in the flow:

Intro / Main Screen
Success Screen
No Luck Screen

For each screen, you can tailor the following elements:

Branding: Adjust background colors, text colors, and upload custom artworks.
Content: Edit the headlines, descriptions, and call-to-action messages to match your tone and messaging.

This allows you to create a fully branded, on-theme experience that aligns with your business identity.

📝 Important Notes:

Fraud Prevention

In the "Slot Machine" campaigns for guests (Audience is Anonymous/Not Logged-in), there was a risk of fraud as users can re-enter the campaign by using a new email address, allowing them to gain additional rewards. To address this, the following improvements have been introduced:

Single play Per Session: Guest users can try the game only once per session. After their initial play, they will be prevented from re-try the same game within the same session. If they attempt to re-enter, a message will display: "You have already spun the Machine."
Multiple Machines in Campaign: For campaigns with multiple machines, this restriction applies individually to each machine. Guests can still roll any other machine they haven't tried, but they cannot re-roll the same machine they’ve already used.
Session Restriction: If a guest opens a new browser tab or window after playing, the same "You have already spun the machine" message will appear to ensure consistent limitations across the session.

Anonymous Option

If you choose Anonymous as the audience, the campaign will be available to visitors who are not yet identified on your store.
Once enabled, a lead form will automatically appear prompting the customer to enter their information (e.g. name, email).
This is a great way to collect leads and retarget potential customers later.
You can fully customize this form by navigating to Customize Design → Lead Form.
