How to utilise this in your designs

After users complete a daily goal, you could let them open a safe to reveal a variable number of coins, turning the end of each session into a moment of anticipation.

Two cards show daily goal completion: "Daily goal conquered!" with a safe icon and XP earned, and "You earned 20 Coins" with an open safe and continue button.

Example from

Mimo

Rather than auto-crediting rewards, you could ask users to actively tap to redeem them, so revealing a random number of gems feels more satisfying and earned.

Mobile app Achievements UI shows badges: Photogenic (Level 1, yellow) with "CLAIM REWARD" button, Legendary (Level 1, blue), Challenger (Level 1, purple) progress bars.

Example from

Duolingo

You could layer variability beyond the reward amount itself, by pairing variable rewards with changing colours and celebration animations each day.

Example from

Finch

Even small interactions could use variable rewards. Try making a 'Like' animation slightly different each time, so a routine tap still feels a little surprising.

UI shows two sets of blue Facebook "Like" thumbs-up icons floating on white background with grey borders; each set highlights "1" inside a blue-bordered white box.

Example from

Asana

When users join a membership scheme, you could let them spin a wheel to reveal a free gift, so the variable reward makes signing up feel like a prize draw.

Example from

Zizzi

Possible impacts

Tying variable rewards to specific actions could increase feature usage, as users return to that feature hoping the next reward will be a bigger one.
