Netherlands-based Digipuzzle is an online educational resource that offers hundreds of G-rated learning games for younger audiences, many in both Spanish and English. Topics include math, animals, typing, geography, spelling, letter recognition, holidays, seasons, dinosaurs, USA, other games, and more. Many of these are divided into subcategories — for example: Math includes games and counting, fractions, addition, subtraction, and multiplication. Digipuzzle even offers holiday games. The site is easy to navigate, fun to use, and completely free. It is the labor of love from Marcel van de Wouw. It includes not only lots of themed puzzles, but Sudoku, line puzzles, search puzzles, dot-to-dot, tangrams, mosaics, and more.
You can use Digipuzzle on the web or as a mobile app.
Each game includes a sidebar with easy-to-understand icons that answer questions, access settings, and click you through available games.
Each game can be played at the level a student is comfortable — easy, normal, or hard — and can include audio or silent.
