Puzzle Tools

LitaRiva puzzle book pipeline — runs entirely on-device. Ordered by workflow: theme → generate → cull → assemble. Themes are the swappable module; every generator consumes them.

1 · Themes

Word LibraryOne word, many themes — tag once, draw everywhere, export lists in the format the generators already read Word ScreeningRule on the library one screen at a time — every verdict banked with a reason, so a word read once is never read again Theme List ManagerThemed word lists with clues — validated, stored, exported, handed off to every generator

2 · Generate

Word SearchFull-enumeration placement — directions, overlap, fill strategy; every word places or fails loudly Difficulty RampNamed tiers as the spec — Easy/Medium/Hard with optional gentle drift; one tier + one list = one book's ZIP MazesBacktracker & Prim's textures — enforced solution-path length, perfect single-path mazes Word ScramblesClued or theme-only — three scramble styles, letter-verified against every answer Number SearchWord search mechanics on digits — random pools or themed lists, ambiguity-checked CryptogramsFresh derangement per quote — frequency-based letter hints, round-trip verified SudokuUnique solution as a hard gate — four tiers graded by technique depth, not clue count Criss-CrossFreeform interlocking fill-ins — run-verified so no unintended words can form

3 · Cull & calibrate

Contact Sheets & CullingKeep/cut every puzzle with tagged reasons — kept ZIP + metric-rich culling log for calibration

4 · Assemble

Book BuilderRun ZIPs → print-ready KDP interior — sections, dividers, solutions in back, direct PDF on iPhone/iPad Cover SpecPage count + trim → exact Canva canvas, spine, folds, safe areas — downloadable SVG guide layer, recipe-stamped Fill ScanA run's manifest → the puzzles whose fill letters spell a slur; letters inside a placed bank word are exempt. Re-roll the flagged ones.
