Every stone carries two letters – one on each side. Place words, then flip stones already on the board: STONE becomes STORE. A word-building roguelite where heavy letters face up drive your Mult, long fresh words send your score soaring, and bosses bend the rules.

SteamAbout JANOLITH
Two letters. One stone. Every flip changes the board.
In JANOLITH, every stone carries two letters – one on the front, one on the back. Place words on an open board, then flip stones that are already down. One flip turns STONE into STORE – and changes every word that stone is part of. Nothing you place is final.
Flip It
The Run
Seven chapters of rising targets. Each round gives you a limited number of moves and discards to hit the target. Pick your path through each chapter – a Small round, a Big round or a trip to the shop – before the Boss is waiting at the end – and at the end of chapter seven, two of them at once. Your bag of stones comes with you through the whole run. Shape it as you go: Gild a stone to make it score double, Rewrite its back, Cleave a weak stone out of the bag or give a strong one a Twin. Open the bag at any time to see every stone of your run – still in the bag, on your rack or on the board.
Bosses & Shop
Twelve bosses, each one changing the rules. The Rust stops placed stones from flipping. The Narrows shrink the board to a strip. The Glut lets each letter score only once per move. The Deadline puts every move on the clock. At the end of every chapter you choose between two bosses: take the milder one, or risk the harsher one for a richer shop. The final boss is a pair: two bosses at once, both in their tougher form – and you choose which pair you face. Spend your crystals on cards that bend the scoring in your favor – 38 of them, from Mirror (words also count read backwards) to Palindrome, Bookends and Turncoat, plus cards that keep growing over the run, like Architect, Tidal Wave and Record Hunter. Level them up, arrange them in your card column and unlock slot mechanics like Opener and Closer.
