Brain Code is a command-line-inspired puzzle game. Read a level, type a command, and use the response to work out what to try next. It’s a game about clues and logic, not a coding lesson. Explore 50 handcrafted levels. Some clues ask you to think beyond the obvious answer. No programming experience is needed: curiosity and careful observation are enough to begin. If you get stuck, optional in-game hints can give you a nudge. You can also leave a puzzle and return to it later. The levels can be played offline. Ready to try a different way of thinking? Start with the first level and see where your next command takes you. Questions or a bug to report? contact.kkapps@gmail.com Reading the description again? The last two lines may help.

About

Trendline

Read full description

Every day, Trendline shows you something real (how the price of oil moved, how a country's population grew, how many people named Karen there are at each age) and hides the answer. You drag a line across a blank chart to draw what you think happened. Then the real data appears, with one honest score and the story behind it. DAILY ROUNDS A fresh puzzle in each of five themes, every day: • World: climate, markets, the economy, technology, nature and space • People: population, sport, culture and society • Ages: draw how a group is spread across ages, from people named Jennifer to Olympic skiers to the users of an app, against everyone else • Sunday Special: one line is drawn for you, you draw the other, and the reveal tells you whether the two things are really connected or only look it • Maths: draw the graph of a function like y = x² + 3x + 1 and get it graded like homework, A+ to F−. The level rises through the week, from a straight line on Monday to a proper brain-teaser on Sunday ONE CLEAR SCORE Your score is the typical distance between your line and the real one, as a share of the chart's height. No hidden formulas: 0% miss is a perfect 100, and every 1% of miss costs 3 points. Small mistakes cost little, big ones add up. LEARN SOMETHING EACH TIME Every reveal gives you the real numbers, a sentence that puts them in context, and the source they came from. Log-scale charts are explained right in the app. KEEP GOING • Build a daily streak by playing each day's puzzle on the day • Catch up on any of the last 7 days from the calendar • Find the hidden trophies: draw certain kinds of line and you may unlock a secret • Turn on an optional daily reminder that skips the days you have already played • Feel each result with subtle haptics • Track your average, your best and your history on the Stats screen COMPETE Sign in to Game Center to see how you rank against players around the world on today's puzzles: one board for first tries and one for best tries. PRIVATE AND SIMPLE No account and no tracking. Your history stays on your device, and the puzzles work offline. The only thing shared is your score on today's puzzle, and only if you sign in to Game Center.
