Stakko is a calm, clever daily puzzle. Slide numbered blocks between stacks until every column matches its goal — a target sequence, a size order, all-same, all-different, and more. Simple to pick up, satisfying to master.
A fresh Daily Challenge lands each morning, plus a seeded Easy, Medium, and Hard for everyone. Build a streak, collect a medal for every day you solve, and watch your calendar fill up.
Daily Challenge — one shared puzzle a day, with a global streak to keep alive.
Easy / Medium / Hard — a curated set every day, sized to your mood.
Gauntlet — a race against the clock: solve as many as you can before time runs out.
Calendar — earn a medal for every daily you complete and revisit past days.
Snappy, magnetic drag-and-drop. Gentle haptics and sound. Clean, readable boards with a size-ramp guide so you always know which way the blocks go. Full VoiceOver support, and it scales beautifully on iPad.
Play as much as you like for free. Stakko+ removes all ads and unlocks every theme, unlimited hints, the full daily archive, and more — $3.99/month or $24.99/year, with a free trial.
