Ordna. Sort puzzles got loud. This one’s quiet.

Three iPhones showing Ordna in a yellow, a painterly and a candy theme: columns of blocks to sort by color.

Ordna (Swedish for “to put in order”) is a minimalist block-sorting puzzle for iPhone and iPad. You sort colored blocks across columns until each column holds one color. That’s all the rules.

A thousand puzzles, no catch

There are a thousand puzzles, all open from the start, and every one of them was solved by a computer before it shipped. No timer, no score and unlimited undo. If you get stuck, a hint shows the next move. A new daily puzzle is the same for everyone.

It’s free, with no ads and no gems. Themes change how Ordna looks, never how it plays, and one purchase unlocks them all.

Accessible from the start

Accessibility was there from the start rather than bolted on afterwards. The default theme uses symbols alongside color, so it’s fully playable for color-blind players. Ordna supports VoiceOver, Voice Control, Larger Text, Dark Interface, Differentiate Without Color Alone, Sufficient Contrast and Reduced Motion, and it’s available in over 30 languages.

Apple featured it in “New games we love” in a lot of countries.

Ordna is one of my own apps, straight out of the Department of Special Projects.
