Daily word game done right. 3-8 letters. Love numbers? Daily number & math games. No ads while playing. Ever. Erudition is a daily brain game that finally gets the details right. Play a fresh word, number, or math puzzle every day, pay one dollar once, and never see an ad or a subscription. No internet required. YOUR STREAK NEVER BREAKS Life happens. Miss a day, or a whole week, and your puzzles simply wait for you. Come back, play your missed days, and your streak keeps right on growing. Play at your own pace without ever being punished for having a life. PLACE LETTERS ANYWHERE Forget filling boxes left to right. Place a letter in any square you like. Know the second and fourth letters? Drop just those two in to picture the answer. Better yet, one tap of the rainbow button sends all your confirmed letters straight to their spots. FIVE COLOR HINTS, NOT THREE Most guessing games give you three clues: right spot, wrong spot, not in the word. Erudition gives you five, so every guess teaches you more. Not sure what a color means? Tap any tile for an instant explanation. GOLF SCORING MAKES EVERY GAME COUNT Every game has its own par, set to the score most players average, with two guesses to spare before you pick up. Finish under par and celebrate a Birdie, an Eagle, or the legendary Hole-in-one, with extra confetti included. It turns a daily puzzle into a score you will actually want to beat. CHOOSE YOUR CHALLENGE Word Game The classic mystery word, but you pick the length: 3 to 8 letter English words, 4 to 5 letter Spanish, or 5 to 6 letter Dutch. Every English answer is a common everyday word, so the game stays fair. Guess wrong and you still learn something: English games show the definition of the answer, and Spanish and Dutch games show its English translation. Genius Word Game For players with a big vocabulary, or players who want to build one. Any valid English word can be the answer, obscure ones included. Do not let Genius scare you off: hints make sure you never get stuck, and you see the definition of every hint and the final answer. Number Game A daily 3 to 5 digit mystery number. Choose all numbers, or prime numbers only for an extra challenge. A perfect first game for young players learning how color hints work. Math Equation Game Solve a daily mystery equation using 6, 7, or 8 tiles. Choose addition and subtraction, multiplication and division, or all four operations at once. SMART FEATURES THAT HAVE YOUR BACK Smart Mode catches color-hint mistakes before you submit, so a careless slip never costs you a perfect game. Stuck? Hints will always guide you to the finish. Word definitions appear after every English game to grow your vocabulary, and Spanish and Dutch games can show English translations to help you learn a new language as you play. A KEYBOARD BUILT FOR PUZZLES Prefer bigger keys? Switch to Erudition's exclusive four-row alphabetical keyboard. The larger keys mean fewer mistyped letters and a more comfortable game. SHARE CARDS THAT KNOW YOUR STORY Win a game and share a beautiful card with a message chosen just for you from over a thousand possibilities. It knows your streaks, your milestones, your comebacks, and even the holidays, so no two are quite the same. FUN FOR EVERY AGE From a five-year-old guessing numbers to a word lover chasing perfect Genius games, there is a daily challenge here for everyone. Track your statistics, watch your averages improve, and challenge your friends to beat your score. START ANYTIME Two full weeks of games are waiting the moment you open the app. Sharpen your mind.
