Logic puzzles for adults

Thirteen puzzles that ask you to plan a few moves ahead and spot the rule.

Logic games in Witilo come in three kinds: move puzzles where you plan ahead (Lights Off, Tube Sort, Untangle, Ink Paths, Pair Lines), spatial puzzles you solve in your head (Paper Fold, Cube Net, Turn Match, Gear Spin), and rule puzzles where you find the pattern (Matrix Gap, Next in Line, Shape Next, Odd by Rule).

Every puzzle is checked to have a solution before you see it.

All 13 logic games

Lights Off
Tapping a lamp flips it and its neighbours. Turn every lamp off.
Tube Sort
Pour until each colour fills a tube of its own.
Gear Spin
The arrow shows how one gear turns. Find which way the ? gear turns. Touching teeth and crossed belts flip the way; open belts and rods keep it.
Untangle
Drag the dots until no thread crosses or touches another and none runs under a dot.
Ink Paths
Join each pair of matching dots with a line. Lines may not cross or pass through other dots. From the expert levels on, every square must be filled too.
Pair Lines
Draw a line from each picture to its twin. Lines may not cross each other, ink blots or other pictures.
Paper Fold
A sheet is folded and punched. Pick how it looks unfolded.
Cube Net
Fold the flat net in your head and pick the cube it makes. Marks and the way they point must match. Some rounds show a cube: pick its net.
Turn Match
Say whether figure B is figure A turned, or A mirrored. Size never counts.
Matrix Gap
The tiles change by rules along the rows or down the columns. Pick the tile that fills the gap.
Next in Line
Find the rule in the row and type the number that comes next.
Shape Next
Figures gain or lose dots or sides, turn, cycle through fills or switch between two looks. Pick the one that comes next.
Odd by Rule
Four figures share a rule: mirror symmetry, even or odd sides or dots, as many dots as sides, or filled only when pointing up. Tap the one that breaks it.
