Some days you want to think in words. Some days you want to think in numbers. Some days you just want to sit with a puzzle and feel your brain work. Puzzle Stack is built for all of those days. Three games live inside the stack: Wordzy, Sudoku and Gridlock. Each one has its own daily puzzle, its own rhythm, and its own streak to protect. Play all three and you’re building three habits at once or just come back for the one you love most. - Wordzy gives you six attempts to find the hidden word. Every guess is a clue. It’s quick, sharp and a new word shows up every morning. - Sudoku is the one you already know. We made it feel really good to play. One clean grid a day, nothing in the way. - Gridlock is a logic puzzle. Fill the right cells, follow the rules, and the grid tells you exactly when you've got it. Miss a day? The archive holds the previous puzzles for each game so you can go back whenever you’re ready. Boosters are earned through play, not purchased. No ads, no countdown timers, no pressure.
