Cerebrum is an offline puzzle games app for iPhone and iPad, made by Synapgeek. It brings classic and newer brain games together in one app: Sudoku, Crossword, Word Search, Minesweeper, Pixel Art (nonograms), Cross Math, Pandoku, Arrow Maze, Trace and Maze.
Every game is free and plays fully offline, no Wi-Fi needed: all the puzzles are already in the app. No game or difficulty level is locked behind a purchase. One daily challenge, one streak to keep, and you never run out of puzzles.
— LOGIC & NUMBER PUZZLES —
Love Sudoku? These grids are solved by pure deduction too.
• Sudoku — the classic 9×9 grid, from Easy to Elite, with notes and hints.
• Pandoku — a Star Battle logic puzzle. Place one panda in every row, column and region, with no two pandas touching, not even diagonally.
• Minesweeper — the classic. Use the numbers to reveal every safe cell and flag every mine.
• Pixel Art — nonograms, also known as hanjie. Fill in cells from the row and column clues to reveal a hidden picture.
• Cross Math — a math crossword. Every "word" in the grid is an equation to complete with numbers from the pool.
— WORD GAMES, IN ENGLISH AND FRENCH —
• Crossword — clue-based grids.
• Word Search — swipe to find the hidden words.
— PATH PUZZLES —
• Trace — a one-line path puzzle. Draw a single path through every cell, hitting the numbers in order.
• Maze — guide your firefly to the exit and collect crystals along the way.
• Arrow Maze — a relaxing arrow puzzle. Tap an arrow to slide it off the board when its way is clear, until the board is empty.
— DAILY CHALLENGE & STREAKS —
• Pick your game each day: everyone gets the same daily puzzle. Missed a day? Catch up from the monthly calendar.
• Complete the challenge every day of a month to earn that month's trophy.
• Your streak grows every day you finish a game. Lost it? An optional ad can bring it back within a few days.
• In the evening, a Live Activity on your Lock Screen counts down the time left to save your streak.
— YOUR PROGRESS —
• A level path for every game and difficulty, rated 1 to 3 stars, then Endless Mode.
• Your avatar grows up with you along the path, from baby to adult.
• Your total score across all games moves you up the leagues, from Bronze to Legend.
• No timer to refill lives and no waiting: after a game over, replay the level right away.
• The Breeze universe is free; unlock Cascade, Lagoon and Blossom with gems.
— GOOD TO KNOW —
• No connection? Every game still works, daily challenge and streak included; progress syncs when you're back online.
• Play as a guest from the very first launch. Signing in with Apple, Google or Facebook is optional and syncs your devices.
• iPhone and iPad, 16 languages, light or dark mode, adjustable sound effects and haptics, VoiceOver support.
— FREE, WITH OR WITHOUT PREMIUM —
• Cerebrum is free and supported by ads: a banner during play and ads between some games.
• Rewarded ads are always optional: gems, a hint or a second chance.
• Premium (weekly, monthly or yearly) removes the banner and the ads between games. It also adds infinite lives, 5 free hints a day in each game, your first mistake forgiven in every puzzle, free daily gems, and double gems after every win.
• In-app purchases: gem packs, and the Movies, Cooking and Travel theme packs (themed crosswords and word searches), which are not included in Premium.
