Keep and restore progress

Save a game deliberately

import {newGame,turnAt,gameProgress,gameFromProgress,gameCode} from "@johnmorrisdotca/suido";
import {SUIDO_5X5} from "@johnmorrisdotca/suido/levels-5x5";
const code = SUIDO_5X5[0][0];
const game = turnAt(newGame(code)!,0);
const kept = gameProgress(game);
const restored = gameFromProgress(code,kept);
console.log(restored?.turns,restored && gameCode(restored)===gameCode(game));

1 true

Keep the original puzzle code alongside progress. The compact progress format preserves the game's turns and facings; gameCode instead describes the current board and cannot preserve the number of taps. gameFromCode reconstructs legal facings with turns set to zero. Both restore functions return null for incompatible input.

Let the host own storage

The SDK returns strings; your host decides whether to offer a download or save them. The iframe stores nothing. An element's progress getter reads the live game and its setter restores a kept string. Listen to suido-change for updated progress, and keep event handling separate from board creation so a callback change does not restart play.

A hint needs a valid matching answer. Counts alone do not prove a board is solved: read flow and validation, then the event contract.
