Mario Kart Tour squeezes Nintendo's premier racing franchise into a single-thumb mobile format. The colorful graphics and real-world city courses look great, but the engine driving the experience is built on loot boxes and microtransactions.
Progressing through higher cups eventually requires specific high-rarity drivers and karts. If you give a kid this app, lock down App Store purchase approvals immediately or prepare for a steady stream of requests for gems and subscription passes.
