## What is Rollo?

Rollo is a one-finger brain puzzle. Swipe: the ball rolls until it hits something and paints its path. Paint is a wall, so you can never cross it again. Fill every tile to finish the level.

You learn the rule in 10 seconds. Mastering it takes much longer: take the wrong order and your own trail traps you in a corner. The simplicity of one line puzzles, the curiosity of mazes and the "got it!" moment of logic games, all in one.

REAL NUMBERS
• The first levels take about 6 seconds: warm-up rounds
• After level 30, 3 in 4 of our players get stuck on the first try
• Those levels take 6 tries on average
How many tries will you need?

1000 LEVELS, ALL SOLVABLE
• Every level is verified by a solver: each one has a solution
• Difficulty rises step by step; every new obstacle is introduced with a live example
• Portals, arrows, cracked tiles, one-way gates, keys and switches turn each level into a new brain teaser

REWARDS EVERY DAY
• Daily reward: come back every day for hints and Solves
• A 7-day calendar with a chest waiting on day 7
• Keep your streak to climb tiers: Bronze, Silver, Gold, Diamond. Higher tiers bring bigger rewards
• Missed a day? You can still save your streak

A NEW PUZZLE EVERY DAY
• The Daily Puzzle is the same for everyone: see how many solved it today
• Finish it without Solve and earn +1 Solve

COMPETE, CLIMB TO THE TOP
• Everyone on the same leaderboards: Daily, Mastery and Levels
• Earn titles from Novice to Genius and show off your badge
• Collect stars on every level: shortest path, first try, no undo

NEVER STUCK
• No lives, no timer: undo a wrong move and try as often as you like
• A hint shows the next right move
• Really stuck? Watch the full solution with Solve

PLAY OFFLINE
• No internet needed: on a plane, on the subway, on holiday
• Your progress is backed up to the cloud, so a new phone picks up where you left off
• Game Center achievements and leaderboards

CALM, CLEAN, YOUR STYLE
• Minimal design with 8 free color themes: Classic, Midnight Blue, Ocean, Forest, Sepia, Sunset, Neon, Lavender
• Light and dark mode
• Soft notes on every move: each level is a little melody
• One finger, portrait mode; 8 languages

Fans of brain games, logic puzzles, mazes, IQ tests and sudoku-style thinking games; anyone who wants a quick mental workout on a break; anyone looking for a relaxing game that is never boring.

On the subway, in line, on a coffee break… Short levels, long fun.
