Relaxing logic puzzle game
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
More than 1,400 calm logic puzzles, each with exactly one solution. Endless play that grows with you, a fresh daily puzzle, and a streak to keep. Works offline.
Looking for a quiet puzzle to end the day with? Welcome to Fireflies, a calm, atmospheric light-up logic puzzle set in a night forest.
Simple Rules, Deep Logic
Place fireflies on the grid so that every empty cell is lit.
• Light the Way: A firefly lights its whole row and column until a tree blocks the way.
• Count the Trees: Numbered trees tell you exactly how many fireflies sit next to them.
• Keep Your Distance: No two fireflies may light each other.
Every puzzle has exactly one solution, so pure logic always gets you there.
Key Features
• Endless Play: Puzzles flow one into the next — gentle at first, sharper as you improve.
• Four Difficulty Levels: From relaxing to properly tough, on grids from 7×7 up to 10×10.
• Daily Puzzle: A new puzzle every day, and a streak to keep. Come back each day and watch it grow.
• Gentle Feedback: Mistakes show up right away, softly — a firefly flickers and fades. You have three lives per puzzle.
• Hints: Stuck? Use a hint to reveal a cell.
• Play Anywhere: Every puzzle is built in, so no connection is needed.
A Calm Corner of Your Day
There's no clock in endless play and no rush. Just a dark forest, a grid, and fireflies waking up one by one until the whole board glows.
Free to Play
Fireflies is free to play and supported by ads. Optional short videos earn you extra hints or let you continue a puzzle. Rather skip the full-screen ads? An optional one-time purchase removes them, and optional hint and life packs are available too.
Ready to light up the forest? Download Fireflies — quiet, warm, and unhurried, a little glow at the end of the day.
Hints now tell you why. After a hint lands, a short step-by-step card shows the reasoning behind it, so you learn the trick instead of just getting the answer. You can turn the card off any time in Settings.
New: Daily Challenge reminders. A gentle nudge when the day's puzzle is ready, only if you want it.
Fixes and polish:
• Fireflies you place now stay put, so an accidental double-tap can't undo them
• Reopening a puzzle you'd already solved now finishes properly
• A softer look for pop-up questions
