CrimeKey: Murder Logic is a detective puzzle game about solving murder cases through observation, clues and deduction. Each case gives you a small mystery: three suspects, three possible weapons and three places where the crime may have happened. Your job is to read the evidence carefully, compare the details and work out the only combination that truly fits. There are no timers, no action sequences and no guessing. CrimeKey is a calm logic game where every mark on the grid brings you closer to the truth. Use the deduction board to organize your investigation. Cross out options that cannot be true, confirm the ones that make sense, and connect suspects, weapons and locations step by step. A stain, a smell, a trace of dust or a small contradiction may be the detail that opens the whole case. Every mystery is designed to be solved by reasoning. Some clues seem simple at first, but only reveal their meaning when combined with others. The solution is always there; you just have to follow the evidence. CrimeKey is ideal for players who enjoy classic detective stories, murder mystery games, logic puzzles and quiet challenges that reward attention. Open the case. Study the clues. Find the key to the crime.

Digital Sudoku is a Sudoku variant with a twist: every clue isn't a printed number, it's a partial seven-segment display, the kind you'd see on an old calculator or digital clock. Some segments are lit, some aren't — read the pattern, decode the digit, and place it. Once you're solving, it's classic Sudoku logic all the way down. FEATURES • Three board sizes — 4×4, 6×6, and full 9×9 — each with Easy, Medium, and Hard difficulties (9×9 adds Expert). • A new Daily puzzle every day, with its own streak to keep going. • Stuck? Hint walks you through the next logical step instead of just filling in the answer — you still have to place it yourself. • Undo/redo, a mistake-checking readout, and an optional timer you can show or hide. • Achievements and stats track your solves, streaks, and best times per board and difficulty. • Compare your times on a real per-puzzle leaderboard. • Light and dark themes, both designed around the seven-segment look. • Play instantly as a guest — no account or sign-up required. Whether you're decoding your first 4×4 or chasing an Expert 9×9 streak, Digital Sudoku turns a familiar puzzle into something you have to look twice at.
