Charge Break: Star Puzzles

Charge Break is a logic puzzle sized for a charging stop. Place one star in every row, every column and every colored region, with no two stars touching, not even at a corner. There is no guessing: each puzzle has one answer that careful thinking alone can reach.

A NEW CHARGE EVERY DAY
• Each day brings a fresh charge set of four puzzles: Spark (5 × 5), Boost (6 × 6), Surge (7 × 7) and Full (8 × 8)
• Everyone gets the same set on the same day, so you can compare notes
• Start small while you plug in, and finish the set before you unplug

ONE TAP PER MOVE
• Tap a square once for ×, twice for a star, and a third time to clear it
• When you place a star, the squares it rules out are marked for you
• Undo any move
• Big squares and large text, made to be easy to hit on a car's touchscreen

BUILT FOR THE CAR, WHILE PARKED
• On cars with Google built in (Android Automotive OS), Charge Break runs on the car's own screen, in landscape or portrait
• It plays only while the car is parked. If the car starts moving, the game steps aside, and your puzzle, marks and clock are waiting when you stop again
• Works with the touchscreen, and with the car's arrow and select controls where it has them
• No sound and no notifications, ever
• No ads on any car screen

THE SAME GAME ON YOUR PHONE
• Play today's charge on your phone wherever you are
• Every move is saved as you make it, so you can put the phone down at any time
• Light and dark looks follow your device's setting

UNLOCK CHARGE BREAK
One purchase, made once, adds:
• Free play: as many puzzles as you like at every size, beyond the daily set
• Overdrive: a 10 × 10 board with two stars in every row, column and region, on screens big enough for it
• Hints that explain themselves: where to look, what follows, and why
• No banner on your phone

PRIVACY
There is no account to make and nothing to sign in to. On the phone, a single banner sits on the home and finish screens, never on the board while you play. Ads there are non-personalized and limited to general-audience content, and players in regions that require it are asked for consent first. On the car, the app shows no ads and collects nothing.
