How to play Takara, Kisha and Tōdai
Takara, Kisha and Tōdai are two free logic puzzles, a new one every day, the two taking turns. The one route to the treasure in Takara, a line for each train in Kisha, or a route the lighthouses count in Tōdai. Every puzzle is built by hand and checked by a solver to have exactly one solution.
The rules
- Find the one route from the entrance to the 宝. It steps up, down, left and right, never crosses a wall, never enters a void, and never visits a square twice.entrancewallvoidtakara
- A number beside a row or column says how many of its squares the route covers. The entrance and the 宝 also count as squares of that row or column. No number means no constraint. A clue with ≥ or ≤ is a bound rather than a count: ≥2 says the route covers at least two squares of that row or column, ≤2 at most two.rowcolumnat leastat most
- An arrow is a square the route must pass through, leaving in the direction it points. A four-way marker only says the route comes through — any way in, any way out. It is drawn with only the ways that are open, so one in a corner has two arms.arrowfour-waycorner
- More than one 宝 means only one is real. The rest are decoys: exactly one sits at the end of a route that satisfies every other clue.特 specialimpostor
Controls
- Draw by dragging across squares in mode. Drag back along a segment to rub it out, or switch to . You do not have to start at the entrance — work back from the treasure if that is easier.
- Mark squares or as notes to yourself. Nothing is checked against them, and drawing a line through one clears it. On a mouse, dragging with erases, and backspace is .
- Zoom with , a two-finger pinch, or ctrl and the wheel. re-centres the board on the screen.
- Move the board by dragging with two fingers, the middle mouse button, or from the margin around the board.
- Your work and your time are kept per puzzle, so you can leave and come back to exactly where you were.
The rules
- Draw one line for each train, in its colour, from its start to its finish. A line steps from square to neighbouring square, may leave its start any way, and never turns round inside a square. Squares no line uses are fine.startfinisha line
- Lines may cross, but only on straights: two lines share a square only when both run straight through it at right angles. Otherwise track never overlaps, and no line runs into a void or a station.crossingvoid
- A station counts the eight squares around it, diagonals included, in which its own train has track — its start and finish count too, and each square counts once. Its number is that count. A station with ? only has to be passed at least once.station? station
- A piece of track printed on the board has to be laid by one of the lines, whichever train it is. A straight piece may still be crossed at right angles.piece
Controls
- Draw by dragging across squares with a train picked in the bar . Pick a train there, or press its start, finish or a station on the board. Drag back along your own track to rub it out, or switch to . Track need not begin at the start — lay the pieces you are sure of anywhere and join them up later.

The rules
- Find the one route from the entrance to the 宝. It steps up, down, left and right, never crosses a wall, never enters a void, a mirror or a lighthouse, and never visits a square twice.entrancea line
- A lighthouse shines four beams, up, down, left and right. A beam turns a corner at a mirror — both faces reflect — and stops at a wall, a void, the edge of the board or another lighthouse.lighthousemirror
- Its number is how many route squares its light falls on. The entrance and the 宝 count, and a square lit twice counts once. Tap a lighthouse to see its light.lit: 3
