Campaign of the Week
McDonald’s levels up with gaming-inspired campaign driving UK footfall /
Fast food giant adds extra life to restaurant visits with in-app Side Missions gaming experience
McDonald’s has tapped into the popularity of gaming culture with a summer campaign focused on a series of daily app-based mini-games that reward customers on completion.
Launched in the UK in July 2025, the campaign celebrates the popularity of ‘side missions’ in video games – challenges that aren’t central to the main game but provide a fun diversion.

Side Missions plays on the idea that McDonald’s delivers similar fun distractions in people’s lives – stopping for food during a long journey, before work, or as part of a shopping trip.
Customers can play each daily mission in the MyMcDonald’s app to unlock food offers throughout the week and instant prizes on weekends – which is designed to drive consistent footfall into stores and sales throughout the summer period.
Developed by tech agency Tms, the games offer a range of challenges and difficulty levels. Each unlocks a specific reward, which include discounts on regular products and the chance to order limited-edition items such as Spicy McNuggets and Jaffa Cakes McFlurry featured on a seasonal Side Missions menu.

Leo Burnett UK created a 60-second film to raise awareness of the Side Missions games. Set to the track ‘Twilight Zone’ by 2Unlimited, it depicts families on ‘side missions’ in life reimagined with classic gaming references.
Out-of-home advertising, influencer marketing, interactive TikTok video and targeted CRM are also used in the campaign. OMD handled media, and TMW managed the CRM activity.
The gaming experience is enhanced by contextual and location-based triggers. Specific challenges are served to fit relevant times of the day, such as starting or leaving work, and the MyMcDonald’s app integrates with mapping service Citymapper to suggest detours to the nearest McDonald’s.
Contagious Insight /
Invitation to play / The campaign was launched to tie-in with the UK school holiday period and offers daily entertainment to bored students. Beyond this, McDonald’s issues an invitation to play to all its customers with games linked to the workplace and family travel.
McDonald’s achieves this by tapping into the popularity of app-based gaming across all demographics while meeting demand for nostalgic experiences – the ads and the games themselves include a distinct retro vibe.
Brands that optimise this balance of playfulness and nostalgia, while connecting generations in shared experiences, have a big opportunity to thrive.
Mattel demonstrated this with the development of its Barbie movie. Lisa McKnight, EVP and chief brand officer at Mattel, told Contagious that it worked hard to target ‘multiple audiences where you can strike a balance between a tone that’s appropriate for a child with some nuanced jokes that go over the child’s head but that adults appreciate’.
McDonald’s strengthens the appeal of its invitation to play because it threads opportunities to participate throughout the campaign. For instance, out-of-home executions include daily digital placements to prompt fans with timely, contextual detours targeting customers in the moments when they might want to side mission to McDonald’s, each headline bespoke to the placement.
The brand has also created a TikTok mission that encourages customers to co-create an experience, and developed partnerships with gaming influencers to create bespoke McDonald’s games for their audiences.
Coupons reimagined / With Side Missions, McDonald’s moves beyond simple app-based discounts towards rewarding customers not only with vouchers but entertainment in exchange for time spent with the brand.
McDonald’s has consistently harnessed gamification in its promotional campaigns (the brand’s long-running Monopoly partnership is the most prominent example) but Side Missions adds layers of interactivity and participation beyond this.
The trend of more sophisticated use of rewards surfaced at Cannes Lions in 2025. Carl Willoughby, chief creative officer of TBWA\Hunt Lascaris and a juror in the Direct category at Cannes Lions, termed this ‘the resurgence of coupons but reimagined’.
Mercado Libre’s Coupon Rain campaign, which won a 2025 Gold Lion in Direct, epitomises this shift towards offering something more compelling to people who are carpet bombed with discounts. The campaign sparked a bargain hunt in Brazil by dropping discount coupon confetti at a big football match and then created an interactive experience that ended with fans winning in terms of discounts and the retailer boosting its sales.
