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. Six games live inside the stack. Four of them, Wordzy, Sudoku, Gridlock and Crossword, have their own daily puzzle, their own rhythm, and their own streak to protect. Play all four and you're building four 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. - Crossword is a mini crossword you can finish over your morning coffee. A small grid, a handful of clues, and a fresh one every day. When you want to keep going after the dailies: - Word Jam gives you a handful of scrambled letters and asks you to find every hidden word. Hundreds of levels, each one a little trickier than the last. - Arrows fills the board with arrows pointing every which way. Tap one and it slides out in its direction, unless something is in the way. Find the right order and clear the board before you run out of lives. Miss a day? The archive holds the previous puzzles for each game so you can go back whenever you're ready. Finish puzzles to earn coins, then spend them on hints when you're stuck.
