Meet the 25-second friend challenge. - Scrub the hand, build combos and earn a score and cleanliness grade. - Share a "Beat my hand" link so a friend can try the same layout and rules in the app or the free browser sample. - Watch your final six seconds, share a scorecard and try the same hand again. - Paused or interrupted rounds become practice. Retry for a comparable attempt. Challenges keep your campaign progress and purchases separate. Dirty Hand remains included with the paid app; Dirty Tooth and Dirty Foot remain optional one-time packs. Friendly challenge scores are self-reported, not verified by a server. No accounts, ads or analytics.

Fixes a crash that prevented the app from opening on iOS 27.

A simpler campaign screen, more varied stages and progress you can return to. • Continue saved campaigns with enemies, boosts and timers restored. • Take on new stage objectives, enemy roles and boss attack patterns. • Hold to scrub and watch each surface become cleaner. • Earn stage grades, organism cards, cosmetic effects and campaign trophies. • Practise cleared stages with a separate save. • Play on a redesigned foot, with guided armour practice and clearer tips. • Improved accessibility, controls and save recovery.

Chill mode is now more forgiving across Dirty Hand, Dirty Tooth and Dirty Foot. - More time between new germs and a gentler build-up through later stages. - Shorter rounds, easier targets and shorter boss fights. - Wider, faster tools and more relief from each clean-up. - More time to recover when the surface is overrun. - New players start in Chill. Your saved mode choice and progress stay intact. - Arcade and Hardcore have also been adjusted for a smoother difficulty curve.

Dirty Foot is now Dirty Hand 2.0, consolidating the related Dirty arcade games into one maintained app. • Play the complete Dirty Hand campaign with the base app. • Add Dirty Tooth or Dirty Foot as a one-time campaign purchase. • Restore Purchases from the campaign screen. • Existing Dirty Foot customers retain the Dirty Foot campaign without paying again. • Keep every campaign installed and play offline after entitlement verification.
