Twin clues across two rows
Every board proved by logic
No ads, no lives
How it plays
A picture logic puzzle with a rule of its own: twin clues that span two rows.
A picture logic puzzle built on twin clues. Most rows are latched in neighbouring pairs, and a raspberry twin number across both counts one shape that touches both rows. All 107 pictures use twin clues, and every board is proved to have exactly one solution, reachable by logic alone. No lives, no fail state, and one shared ranked Daily.
- Twin clues: one number spans two latched rows
- 107 pictures on 5×5, 10×10 and 15×15 boards, all with twin clues
- Every board proved to have one solution, reachable by logic alone
- One shared ranked Daily, replayed on the server before it counts

What is inside
Inside Twinlatch.
One clue spans two rows
A latched pair of rows shares its clues. A raspberry twin number drawn across both counts a single shape that touches both rows, cells joined edge to edge, never diagonally. The pair's other numbers each belong to the one row they sit in.
Every board is proved
Every ladder board, every practice board and every Daily is checked by the app's solver for exactly one solution and a path to it with no guessing, twin clues included.
Paint a whole thought
Fill or cross several cells in one stroke, then undo or redo that stroke as a single decision. A loupe magnifies the cell under your finger on large boards, and a solved board develops from ink into a coloured picture for your gallery.
Ask for logic, not an answer
The optional hint reveals one cell that follows logically from the board as it stands, and it is fully undoable. It is off on today's Daily for everyone, so paid access never changes the competition.
Quick answers
Twinlatch questions, answered
How do you play Twinlatch?
Fill the cells the clues call for to reveal a picture. Column clues and unlatched row clues are runs of filled cells. Most rows are latched in neighbouring pairs, and a raspberry twin number drawn across both rows counts one shape that touches both, cells joined edge to edge, never diagonally. Every board is proved to have one solution, reachable by logic alone.
