Farmer & Stone

A sliding-block puzzle on the classic klotski skeleton: a 4×5 board, a two-cell gate at the bottom, and only two kinds of pieces — the farmer (a big 2×2 block) and stones (1×1 pebbles plus 1×2 slabs, lying flat or standing up). Every piece can be picked up and slid: tap it, drag it, or nudge it with the arrow keys, one cell at a time, as long as the cells it is heading into are empty. There are no timers, no fail states and no extra laws — the whole puzzle is where the stones are piled and how you unpick them. Three ways to play: Stroll (five empty cells to breathe), Classic (five slabs, four pebbles, only two empty cells — real sliding-block density) and Siege (six slabs, almost nowhere to retreat). Every deal is drawn from a built-in deck whose layouts were generated and machine-checked in advance: each one is solvable, each one needs real work, and no layout is ever a one-move win.

Triad

A shape-logic puzzle built from three primitives: a square, a circle and a triangle. Each walks its own way — the square steps one cell orthogonally and is the only one that pushes crates, the circle rolls until something stops it, the triangle moves diagonally and is the only one that can stand inside a pit. You move one shape per turn, so every level is a small argument about order. Twenty-four hand-built levels, all machine-verified solvable, no timers, no fail states, no downloads.

Fold Realm

A calm spatial-illusion puzzle told as a fairy tale in four chapters. Turn the world until broken planes appear to join, fold pages, turn towers, call bridges on the wind, raise the tide, light lamps that make hidden roads real, and find the one angle that unlocks a door. Twenty-four hand-built pages, each with a single way through, no timers, no fail states.
