SudoQ: Sudoku for Developers

Eleven rule sets, a daily board that is the same for everyone and a career ladder from Script Kiddie to CTO. Pay once: no ads, no subscription.

Sudoku for people who live in the terminal. Clean logic, a monospace look and a sense of humour. No ads, no energy timers, no subscription.

DAILY CHALLENGE One board a day, the same for every player. The week ramps up from a gentle Monday to a tough Saturday, and Sunday brings a variant. Keep your streak going, then share your result.

CLASSIC CAREER Six levels from Script Kiddie to CTO, ten boards each. Every puzzle has exactly one solution and is graded by the techniques it takes, from singles to X-Wing. Boards open one at a time as you climb.

HINTS THAT EXPLAIN Stuck? A hint names the technique that finds the next digit and shows you where to look. Ask again and it reveals the digit.

ROOT ACCESS: ONE-TIME PURCHASE • Variants: Killer, Thermo, Arrow, Diagonal, Windoku, Odd/Even, Consecutive, Renban, Anti-Knight, German Whispers and Palindrome. Three levels each, and a fresh board every time. • Dev Mode: ten tickets that bend the rules, with digits 0–8, binary, isPrime, powers of two, fib() and a hotfix in production. • Ranking: endless runs with three lives and difficulty that keeps climbing.
