Kingfisher six-by-six habitat puzzle with placed birds and exclusion marks Habitat logic

Solo logic puzzle

Kingfisher

Place exactly one bird in every row, column, and outlined habitat. Birds cannot touch—not even at diagonal corners—so every placement changes several parts of the board at once.

Start with a guided Journey or choose another board in the web edition. Tap a cell to cycle between a bird, an exclusion mark, and an open square. The satisfying part is the chain reaction: one forced bird can close a habitat, finish a row, and expose the next safe landing place.

Solo logic puzzle

Sundown

Fill every cell with a sun or moon while passing four tests: balance every row and column, prevent runs of three matching symbols, satisfy every equals-or-differs clue, and keep completed rows and columns unique.

Local patterns make this approachable: sun–blank–sun forces a moon, while a completed quota fills the rest of a line with the opposite symbol. Larger boards make those same rules interact across more cells, and the built-in hint system can explain a logical next step when you stall.

Rainbow Rumble

Match the discard pile by color, number, or symbol, use action cards to interrupt the table, and be the first player to empty your hand.

Play with people sharing the screen, computer rivals, or a mix of both. The setup panel supports two to four total players and optional rules including learning mode for kids, jump-ins, stacking, sevens-and-zeros, and draw-to-a-match. Remember to call “Rumble!” before you play down to one card.

I Spy Adventures

A child-directed search game built for young players, including pre-readers. Picture previews and spoken clues name each treasure, while friendly hints help the search continue without turning a missed tap into a dead end.

Pick from twelve illustrated worlds, from Rainbow Castle to Tiny Town Traffic. Easy asks for six large finds with visual zones; Tricky asks for eight smaller finds with verbal clues; Expert asks for ten, adds decoys and partially hidden objects, and allows closer zooming. Finishing a round earns a sticker for a saved-in-browser sticker book.

Solo deduction mystery

Wax Key

Build the case, test every claim, and rule out the rest. Each mystery asks you to connect suspects with evidence, locations, and motives until one provable solution remains.

Thirty cases are playable in sequence. Read the case material carefully, compare statements and timelines, then use contradictions to eliminate possibilities rather than trusting the first plausible story. Progress stays in your browser, so you can leave a longer case and return later.
