jirafaGraph is a number puzzle played on a clock, set to music. Every node of the graph holds a number. You start on one node with a value. Tap a neighbouring node and its number is added to yours, clock-style: go past the top and you wrap around to 0. Reach the target value, then the next one. Ten targets make a game. LEARN AS YOU PLAY Your first game is a short interactive tutorial: five small puzzles that teach the rules one at a time. Skip it if you like, and replay it any time from "How to play" in the menu, along with a second lesson for the bigger levels. EVERY MOVE IS MUSIC Each value is a pitch, played by recorded percussion, and every number on every clock has a pitch of its own, from 4 hours to 90. Every move plays a short three-note motif: where you are, where you need to be, and back again. Finish a game and you have composed a melody. A PUZZLE A DAY From 1 November 2026, a new daily puzzle every day, the same for everyone, arriving at midnight your time. Monday is the gentlest, the weekend the hardest. Each day also has a twist, and a calendar keeps your scores. Keep your streak going. FOUR jirafaPacks, FOUR WAYS TO PLAY Choose a jirafaPack: • Baby: small clocks, from 4 hours up to 12, with a clock face on screen and a glowing hint in the early levels. • Toddler: a 12-hour clock that gains six hours every ten levels. • Teen: a 30-hour clock. • Adult: a clock that keeps growing, and a graph that grows as you play. Beyond Baby, some levels grow new branches after each target, and some numbers keep changing until you land on them. THE GARDEN A jirafaPack where every level grows where you play. Reach a target and the plant puts out new branches beside you, with new numbers to use. An acacia, a fern and a snowflake take turns. CHAPTERS AND ACHIEVEMENTS Baby, Toddler, Teen and Adult have chapters: pairs of hand-made levels built around one idea, such as going round the clock. Play offers them, never forces them. Achievements wait behind the star in the menu, each explained in one sentence. PAR, STARS AND CHARLIE Every target has a par: the fewest moves that can reach it. Reach it at par for 100 points and three stars; a perfect game scores 1000. Charlie, the rival giraffe, always takes one move more than par. Tie him for two stars, beat him for three. Time is shown at the end but never counts against you. After each game the summary shows your score, the stars for every target, your moves against Charlie's, and your best score in that jirafaPack. Tap Share to send a friend your stars and a link to the very same puzzle. PLAYS NICELY • No ads. • Works offline. • In English and French, following your iPhone's language. • Follows Reduce Motion, and taps are more forgiving on small nodes. • Works with VoiceOver, and with a keyboard: Tab, the arrow keys, Return, Space and Escape. • Follows your iPhone's text size in menus and other reading text. • Sound on or off from the menu. The game follows the silent switch and lets your own music keep playing. TEEN, ADULT AND GARDEN Baby, Toddler and the daily puzzle are yours to play, and so are puzzles friends share with you (shared Garden puzzles: three a day without Garden). The Teen and Adult jirafaPacks are one in-app purchase that opens both for good, with past dailies in the calendar. Garden is a separate in-app purchase that opens the Garden jirafaPack for good. Family Sharing lets your family play them too.
