New game: River Crossing. Ferry the wolf, the goat and the cabbage, then wolves, sheep, oxen and a sheepdog, across 40 levels.
Eight classic math and logic puzzles in one app. No ads. No accounts. Just puzzles.
GAMES INCLUDED:
- Water Jugs — Measure a target volume by filling, emptying, and pouring between jugs. Based on Bezout's identity and the Extended Euclidean Algorithm.
- Tower of Hanoi — Move stacked disks between rods without placing a larger disk on a smaller one. Includes the classic 3-rod puzzle and the 4-peg Frame-Stewart variant with a custom sandbox mode.
- Sliding Puzzle — Arrange numbered tiles in order on grids from 3x3 to 6x6. The original 15-puzzle, popularized in the 1880s.
- Lights Out — Toggle lights on a grid where each press flips neighboring lights. Rooted in linear algebra over GF(2).
- Knight's Tour — Guide a chess knight to visit every square exactly once. Studied by Euler, solved by Warnsdorff's heuristic.
- Egyptian Fractions — Decompose fractions into sums of distinct unit fractions. Features authentic hieroglyphic numeral display.
- Turntables — Rotate interlocking rings to arrange colored tokens. A physical model of permutation groups and Hungarian Rings.
- River Crossing — Ferry the wolf, the goat and the cabbage (and later wolves, sheep, oxen and a sheepdog) across the river without anyone getting eaten. Alcuin's 1,200-year-old puzzle and the missionaries-and-cannibals problem.

NEW GAME: RIVER CROSSING
The 1,200-year-old wolf, goat and cabbage puzzle, plus the classic missionaries-and-cannibals problem reimagined as wolves and sheep. Four chapters, each adding one twist:
- The Farmer's Ferry: the farmer rows, and keeps the peace on whichever bank he's on
- Wolves & Sheep: no farmer, the animals row themselves, and wolves eat sheep wherever they outnumber them
- Heavy Cargo: oxen take two seats, and some passengers can't row
- Expert: everything at once, up to 23 crossings
Free Play generates fresh crossings on demand, and "The Math" explains the graph theory behind it.
