Turn Spanish vocabulary into an addictive puzzle. Lingoburst is a 2048-style grid game where you slide tiles, match English and Spanish words, and clear the board in satisfying bursts. No boring flashcards – just quick, high-focus rounds that actually make vocab stick. How it works: - Slide tiles up, down, left or right. - Burn blockers to make your way. - Match an English word with its Spanish translation. - Hit a correct pair and every tile with that word explodes off the board. - Clear all the words in a level to unlock the next theme. Every move is a mini language test. You're actively recalling words under gentle pressure, which is exactly what your brain needs to remember them. Learn Spanish through play -> Game-first design – built around a 2048-style grid with satisfying tile physics and board-clearing combos. -> Real-life vocabulary – topics like Food & Drink, Travel, Home, Work, Hobbies, Technology, Nature and more. -> Level-based worlds – each theme becomes a little world to conquer, with increasingly tricky word sets. -> Burst mechanic – matching a word doesn’t just give points; it wipes that word from the whole board, rewarding real understanding. -> Spaced practice feel – words reappear in fresh combinations so you meet them again and again in new contexts. Perfect for: - Beginners who want to start learning Spanish without textbooks. - False beginners and rusty learners who know “a bit” but want to unlock more vocab. - Gamers who love 2048, match puzzles or roguelite runs and want something that actually teaches them something useful. Why LingoBurst works: - Short sessions, real progress – each game only takes a few minutes, so you can play on the train, in a queue or on a break. - Active recall, not passive tapping – to clear a word, you must know the match, not just guess from multiple choice. - Theme-based learning – vocabulary is bundled into everyday situations, which makes it easier to remember and use in real life. Whether you’re just starting Spanish or adding vocab on top of classes or Duolingo, Lingoburst turns memorising words into something you actually want to do. Slide. Match. Burst. Learn Spanish while you play.
