Daily word & number game done right. No ads while playing. Ever. No internet required. Erudition Lite is a daily word and number puzzle game that gets the details right. Play a fresh word or number puzzle every day, and never see an ad or a subscription. 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. ENTER LETTERS IN ANY ORDER Forget filling boxes left to right. Place a letter in any square you like, in whatever order helps you think through the answer. FIVE COLOR HINTS, NOT THREE Most guessing games give you three clues: right spot, wrong spot, not in the word. Erudition Lite gives you five, so every guess teaches you more. 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. It turns a daily puzzle into a score you will actually want to beat. TWO DAILY CHALLENGES Word Game A new 4 letter mystery word every day. Every answer is a common everyday word, so the game stays fair. Number Game A new 4 digit mystery number every day. A perfect game for players of any age, young or old. SMART MODE HAS YOUR BACK Smart Mode catches color-hint mistakes before you submit, so a careless slip never costs you a perfect 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.
