TLDR
Most loyalty programs ask customers to do one thing: keep spending until they reach a reward. The problem is that everyone already knows what comes next. Buy nine coffees, get the tenth free. Visit five times, unlock a discount. After the first few visits, the experience becomes predictable. Customers stop thinking about it.
Games change that.
A simple spin, scratch card, or mystery reward creates a small moment of excitement after an order. The customer still receives value, but now there is also curiosity. "What will I get this time?" That single question can make a routine purchase feel fresh again. Research has even found that adding gamification to loyalty programs can make customers focus less on the exact size of the reward and respond more positively to the overall experience. This helps businesses create stronger loyalty without relying on larger discounts.
For restaurants and coffee shops, this opens up a different way to think about customer retention. Loyalty no longer has to feel like a long checklist. It can become something customers genuinely look forward to.

Why Variable Rewards Keep Customers Coming Back
People enjoy progress. They also enjoy surprises.
Traditional punch cards are built around progress. Every purchase moves customers one step closer to a known reward. That works, but only after several visits. Between the first purchase and the final reward, there is very little excitement.
Variable rewards introduce a second motivation. Instead of waiting until the end, customers receive an opportunity every time they qualify. They may win a few bonus points, a free topping, double rewards, or a larger prize. They know something is coming, but they do not know exactly what.
That uncertainty keeps the experience interesting.
The brain pays attention to the unexpected
Behavioral psychology has studied this for decades. Rewards that arrive on an unpredictable schedule often create stronger engagement than rewards that always arrive at fixed intervals. It is one of the reasons games, collectible products, and even surprise gifts feel memorable.
The important point for restaurants is not to copy gambling mechanics. It is to understand a simple human behavior.
People naturally pay closer attention when the outcome is uncertain.
A customer who already planned to buy coffee may become curious about the reward waiting after checkout. That extra moment of anticipation makes visits feel different from the last one.
Instead of thinking, "I still need six more purchases," they think, "I wonder what I'll unlock today."
That shift matters because loyalty programs compete for attention as much as discounts.
Small rewards can still feel exciting
Many restaurants assume loyalty programs require expensive giveaways.
Research suggests something interesting instead.
When gamification is added, customers become less focused on comparing the exact value of every reward. The experience itself becomes part of what they enjoy. Even modest rewards can feel satisfying because the interaction adds entertainment alongside the benefit.
For example, instead of offering:
- Buy 10 drinks, get one free
A merchant could offer qualifying customers a chance to:
- Win 20 bonus points
- Unlock double points on the next order
- Receive a free extra shot
- Get a free pastry once in a while
- Land a larger surprise reward on rare occasions
Most customers will receive smaller prizes. Occasionally, someone wins something bigger. Those moments become memorable because they are unexpected.
The business still controls costs, while customers feel like every qualifying purchase has something new to offer.
Surprise creates conversations
Think about how people talk about rewards.
Almost nobody tells their friends they filled another square on a punch card.
People do share unexpected wins.
"I ordered lunch and got free dessert."
"I spun the wheel and won double points."
"I actually landed the biggest prize."
Those moments create stories. Stories naturally spread through conversations, screenshots, and social media.
That gives merchants something traditional loyalty programs rarely generate: organic excitement.
The reward becomes part of the experience instead of simply being a future discount.
Fixed rewards still have a place
This does not mean traditional loyalty programs are outdated.
Predictable rewards remain useful because customers like knowing they are always working toward something valuable.
The strongest programs often combine both ideas.
Customers continue earning points over time while also unlocking occasional game-based rewards after qualifying actions such as their first signup, a successful checkout, or other milestones chosen by the merchant.
That combination satisfies two different motivations.
One rewards consistency.
The other rewards curiosity.
Together, they keep loyalty feeling active instead of repetitive.

How to Set Your Game Rewards Without Hurting Your Profit
A good rewards game should feel exciting for customers and sustainable for your business.
The biggest mistake businesses make is assuming every spin or scratch card needs a large prize. It does not. The goal is to create a fun experience that encourages another visit, not to give away expensive products every day.
The good news is that you stay in control. You decide when customers qualify to play, what prizes are available, and how often bigger rewards appear.
Start with a minimum spend
One of the easiest ways to protect your margin is by requiring a minimum order value before a customer unlocks a game.
For example:
- Spend $10 to unlock a spin.
- Spend $20 to receive two chances.
- First order over $15 earns a scratch card.
This encourages customers to add one more item to their order instead of redeeming rewards on very small purchases.
If your average ticket is $12, setting a $15 game threshold could naturally increase basket size without feeling forced.
Make small rewards the most common outcome
Not every reward should be a free meal.
Most winning results should have a low cost but still provide value.
Examples include:
- 10 bonus loyalty points
- Double points on the next purchase
- Free syrup or topping
- Small drink upgrade
- Free cookie with the next order
- Entry into a monthly raffle
These rewards cost very little while giving customers another reason to return.
Reserve larger prizes for rare moments.
For example:
- Free entrée
- $20 store credit
- Exclusive merchandise
- VIP reward
Because customers know these prizes exist, they remain exciting even if only a few people win them.
Match prizes to your margins
Every menu has items that cost less to give away than others.
A bakery may find that an extra cookie has a much lower cost than a specialty cake.
A coffee shop may prefer offering flavored syrup, oat milk upgrades, or bonus points instead of free large drinks.
A restaurant could reward customers with appetizers that introduce dishes they may order again later.
The best rewards often highlight products customers have not tried before. A free sample today can become a paid favorite next month.
Review performance after launch
Launching a game is only the beginning.
Watch a few simple numbers over the following weeks.
Ask questions like:
- Are customers spending more before qualifying?
- Which rewards get redeemed the most?
- Are repeat visits increasing?
- Are food costs staying within your target?
- Which prizes generate the most excitement?
Small adjustments usually make a much bigger difference than completely changing the program.
You might discover that customers love earning bonus points almost as much as free products. That lets you keep the experience engaging while protecting your margins.
The best loyalty programs are never set once and forgotten. They improve over time as you learn what your customers respond to.
Loyalty Should Feel Fun Again
Many loyalty programs have started to feel invisible.
Customers collect points without thinking about them. Restaurants keep offering the same rewards year after year. Eventually, the program becomes another feature people expect rather than something they enjoy.
That is changing.
Consumers already interact with games, challenges, and surprise rewards across many of the apps they use every day. They expect digital experiences to feel engaging, not transactional. You have an opportunity to bring that same energy into loyalty without making it complicated.
A quick spin after checkout. A scratch card after a first order. A mystery reward that appears at the right moment. These are small interactions, but they create positive memories that last longer than another predictable discount.
At Per Diem, we believe loyalty should encourage habits while also giving customers a reason to smile. That is why merchants can reward customers after a successful checkout, after signing up, or both, using interactive games such as Spin the Wheel, Scratch Card, Pick a Box, Lucky Slots, or a Raffle Draw. Every merchant decides how customers qualify, which games to offer, and what rewards are available, making the experience fit their brand instead of following a one-size-fits-all approach.
The future of loyalty is not about giving away bigger rewards.
It is about creating experiences people want to come back for.
When every qualifying visit has the chance to surprise someone, loyalty becomes something customers actively look forward to instead of something they occasionally remember.
That is how repeat visits grow naturally, and that is what keeps your app top of mind long after the first order.
