Put every symbol in one row, each used once.
Each symbol has to make a Bliss word with the one before it: knife then animal makes slaughter, animal then feeling makes pet.
Only symbols that can come next are lit. The word list shows every word on the board, so you can plan ahead. If nothing is lit before the row is full, undo and try another order. Each board has one order that works.
Tap or click — places a lit symbol
← → then Enter — places by key
Z — takes one back; H — shows the next one
Bliss builds words by setting symbols side by side, the first usually saying what kind of thing it is. The row is a word chain, like the Japanese game shiritori, and finding it is finding a Hamiltonian path, the puzzle of William Rowan Hamilton's Icosian game (1857).
