The rules
The three rules.
Numeric clues tell you what to light
The numbers around the grid define exactly which cells must be lit. Every board is solved by deduction alone — there is always a next logical step, and never a guess.
Every lit cell joins one connected chain
All lit cells must link edge-to-edge into a single continuous chain. No islands, no disconnected clusters — if a lit group can't reach the rest, the solution is wrong.
No 2×2 block of lit cells
Anywhere four adjacent cells would all be lit at once, the puzzle breaks. This single constraint is what forces the chain to wind, and what makes late-week boards genuinely hard.

FAQ
Frequently asked questions.
What is Wickgrid?
A daily logic grid puzzle for iPhone and iPad. Light the correct cells using numeric clues, form one connected chain, and avoid any 2×2 block of lit cells. A new puzzle releases every day.
Is Wickgrid free to play?
Yes — the daily puzzle and your last 7 days are always free. Wickgrid Plus is a one-time $4.99 unlock for the full archive, unlimited hints, Streak Freeze, and advanced stats. No subscriptions, no ads.
How is Wickgrid different from Sudoku or Nonogram?
Sudoku is number placement. Nonogram fills a picture from row and column counts. Wickgrid has its own rule set — light cells so they form one connected chain with no 2×2 block ever lit — that rewards the same style of careful deduction with a different set of constraints.
Does Wickgrid have ads or collect data?
No. Wickgrid runs fully offline, needs no account, and collects no data, at any tier.
What platforms is Wickgrid on?
iPhone and iPad, requiring iOS 17 or later.
