Start every day with one riddle. MindSpark gives you a single hand-written
puzzle each day — a classic riddle, a lateral-thinking mystery, a word twist,
or a hidden number pattern — and asks you to solve it before you move on with
your day. No feed to scroll, no timer pressure, no ads between rounds. Just
one good puzzle, once a day, the same way a crossword or a word-of-the-day
habit works.

Open the app and today's puzzle is already waiting on the Today tab. Read the
prompt, type your answer (or pick from multiple choice for pattern puzzles),
and tap Solve. Stuck? Reveal a hint — each one costs a star, so a clean solve
without hints earns the full three stars, and the app tracks exactly how you
solved it: on the first try, with a hint, or after a few attempts. Every
correct answer keeps your daily streak alive; miss a whole day and the streak
resets, but MindSpark gives you one grace day so a single busy evening doesn't
wipe out a two-week run.

KEY FEATURES
✓ One new puzzle a day — five puzzle types in rotation, from classic riddles
and "what am I" clues to lateral-thinking mysteries, word-twist anagrams,
and hidden number or letter patterns
✓ Streak tracking with a one-day grace period, plus milestone badges at 3, 7,
14, 30, 60, and 100-day streaks
✓ A full archive calendar of every day you've played — tap any past day to
replay it and chase a cleaner, hint-free solve
✓ A star rating on every solve (3 stars for no hints, fewer for each hint
used) so your archive shows how you actually solved each puzzle, not just
that you solved it
✓ A stats screen with your current and best streak, total puzzles solved,
your cleanest and trickiest puzzle types, days since your last hint, and a
12-week solve chart
✓ Optional hints — up to two per puzzle, revealed only when you ask for them
✓ Haptic feedback you can turn off with one switch, and a one-tap way to
reset your whole history if you ever want a clean start

HOW IT WORKS
1. Open MindSpark and read today's puzzle on the Today tab.
2. Type or select your answer and tap the gold Solve button — reveal a hint
first if you want a nudge, at the cost of a star.
3. Check the Archive tab any time to see every day you've played, and tap a
past day to replay it for a cleaner run.
4. Check the Stats tab to watch your streak, your milestones, and your
12-week solving trend grow over time.

WHY MINDSPARK — it's built to be a short, calm daily habit rather than
another app competing for your attention. There's no feed, no push-notification
spam, no in-app purchases, and no advertising anywhere in the app. The whole
puzzle set ships with the app, so today's riddle loads instantly whether or
not you have a signal.

PRIVACY — MindSpark works fully offline. There's no account to create, no
sign-in, and no data ever leaves your device: your solves, streak, and stats
are stored locally on your phone and nowhere else. The only device permission
the app requests is vibration, used solely for the optional haptic feedback
you can switch off in Settings.
