Diem offers a fresh set of short brain games every day. Open the app for a calm, 5-to-15-minute session that feels like play, not homework. If you enjoy daily puzzles and logic challenges, Diem is made for you.

Your Daily Games
• A new set of games every day, the same for every player that day.
• Choose Quick (3 games), Standard (5) or Deep (8) to fit your schedule.
• Not in the mood for one of them? Swap it for another game of the same skill.
• Diem of the Day: one shared logic puzzle for everyone, with a new board every morning. Three mistakes and it's over. An optional leaderboard shows how everyone did.

Play With Friends
• Add friends with a link or a short code. No requests to accept.
• See who solved Diem of the Day fastest and compare today's scores.
• Keep a streak together on the days you both play, and send a friendly nudge.
• Friends see your daily results; the public leaderboards stay your choice.

26 Games Across 6 Skills
• Logic: Mini Sudoku, What's Next?, Rule Switch and Turn It.
• Memory: Memory Grid, Card Pairs, Echo, Two Back, Where Was It? and more.
• Words: Word Scramble, Word Pick and Good or Bad?
• Numbers: Quick Math, Chain Math, Clock Gap, Head Count, Number Spots and more.

Progress At Your Own Pace
• 100 levels in every game, from easy to expert, with a clear map of your climb.
• Each chapter brings one new idea, so the puzzles stay fresh.
• A wrong move never ends a level. Every mistake tells you why in one plain sentence, and you can use a hint or see the answer.
• Choose Easy, Normal or Hard in Settings.
• Endless mode: Make the number (Quick Math), Spot the shared one (Snap Match) and Word Scramble. Keep going and beat your best.
