More time
The default clock is 25 seconds per prompt. If typing is slow for you, if you are playing on a small screen, or if English is not your first language, switch on More time in Settings (the three dots at the top right). You then get 60 seconds per prompt. Flights played this way are marked as assisted when you share them, so nobody is misled about how they were played.
Reduce motion
Thin Air uses a lot of movement: clouds drift, the plane bobs and the world scrolls as you climb. The Reduce motion switch removes most of it. It starts from your device’s own setting, and your choice in the game then takes priority, so you can turn motion on or off whatever your phone says.
Sound
Sound effects are off by default and can be turned on with the speaker button or the Sound switch in Settings. The game is fully playable without sound; no information is conveyed only by audio.
Colour, contrast and zoom
Information in Thin Air is never carried by colour alone. Every verdict has a name and an icon as well as a colour, and your score is always shown as a number. Text sits on light cream or dark navy panels with strong contrast. The game and every page of this site work on narrow phone screens and when you enlarge the text or zoom the page, without sideways scrolling.
Spelling, words and language
Prompts are written in English and answers are matched after ignoring capital letters, accents and most punctuation, so “Cafe” and “Café” are the same answer. Plurals are accepted, and clear one-letter slips are corrected for you. We add alternative names and spellings wherever we know them (for example “aubergine” and “eggplant”), but we do not catch every regional word. If an answer you would expect is missing, tell us and we will add it. Players who are learning English may find More time helpful, and the verdict names are simple on purpose.
Keyboard and screen readers
You can play from start to finish with the keyboard: type your answer, press Enter to climb, and Enter again to move on. Important changes such as the time remaining, your verdict and your final score are announced to screen readers. If something does not work well with your assistive technology, please tell us; we take it seriously.
