Public change record
We publish meaningful game fixes here so families, educators, and contributors can see the work without needing a developer account. Entries describe the product, not who worked on it: no contributor names, email addresses, or exact work times are shown.
Added a player-paced map mode that names each of all 50 states exactly once in a shuffled session. Players choose the state on the map, retry without a penalty, and decide when to move to the next state; there is no timer or score in this mode.
Added Sudoku entry undo and accurate Solitaire undo availability, strengthened complete-ending playtests for Memory and both Go Fish styles, enlarged Rules and spatial slice controls, and added a file-only audit covering all 27 games for keyboard starts, live status, accessible names, 44-pixel controls, phone-to-desktop layouts, declared chance, and forbidden browser capabilities.
Added a reusable offline shell for game tabs, live status, active-game undo, rules, guide state, board view, print, and keyboard tab navigation. A runtime contract audit verifies all 27 panels, while shared undo delegates to each game's existing history and never changes its rules.
Added an adult-initiated print-and-play view that sends only the active game's current rendered position and visible rules to the browser print dialog. Printing leaves every game state unchanged and creates no upload, saved game, server-side file, or share link.
Added optional First open and Line aware Tic-tac-toe computer behaviors while keeping local two-player as default. Each behavior explains its exact deterministic priorities, replies immediately on-device, groups the local move and reply as one backward/forward history turn, and passed exhaustive legal-choice tests across 294,778 reachable unfinished boards.
Added Previous turn and Next turn history to regular Checkers and Position Builder Explore. Whole-turn states, chained captures, natural endings, and side to move restore exactly; making a new turn after stepping backward clears the old future branch, while the immutable built source remains unchanged.
Added a local Checkers Position Builder with five named edit tools, playable-square enforcement, twelve-piece limits, side-to-move choice, edit undo, validation, a two-jump sample, and Explore mode using forced captures, chains, crowning, natural endings, and whole-turn undo while the built source remains immutable.
Added global Standard, Large pieces, and High contrast board views. The settings are local to the open page, never alter game state or rules, preserve keyboard paths and non-color labels, and passed phone and desktop visual checks plus 40 complete browser scenarios.
Added five finite Spatial Rules Laboratory stations for canonical coordinates, four rotations, three slice planes, view-invariant legal moves, and immutable Before/Route/After replays with named source, destination, direction, resulting check, keyboard controls, and complete browser playtests.
Added five fixed Timeline Chess puzzles over reduced 4×4×4 Space Chess with immutable A/B history, non-interacting saved boards, full-cube self-check filtering, branch-local promotion, slice-invariant legality, active-state check narration, exhaustive mate proof, undo, keyboard controls, and complete browser playtests.
Added five fixed Timeline Checkers puzzles with named A/B states, marked earlier forks, complete multi-jump branch turns, global forced captures, delayed crowning, visible coordinates, immutable original history, branch undo, keyboard controls, and browser playtests proving every branch and undo.
Added five fixed 4×4×4 Space Chess puzzles with kings, rooks, bishops, and pawns; stable L/R/C coordinates; interchangeable slice views; full-cube attack detection and self-check filtering; narrated check sources and directions; rook/bishop promotion; checkmate and stalemate proof; undo; keyboard controls; and complete browser playtests.
Added five fixed 4×4×4 Cube Checkers puzzles with stable L/R/C coordinates, interchangeable layer, row, and column slices, global forced captures, 12 face-diagonal king directions, chained jumps, whole-turn undo, keyboard controls, and complete browser playtests for every puzzle.
Added five cooperative Layered Checkers puzzles across three 8×8 boards with labelled paired portals, global forced captures, cross-layer jump chains, portal crowning, isolated layer views, whole-turn undo, keyboard controls, and complete browser playtests for every puzzle.
Added three fixed offline 8×8 Minesweeper boards with guaranteed-safe first reveals, Reveal and Flag modes, blank-area opening, calm no-timer endings, reset, undo, keyboard controls, and complete playtests for every board.
Added three fixed offline Code Breaker puzzles with named shapes plus colors, duplicate-aware exact and elsewhere clues, calm eight-guess endings, reset, undo, keyboard controls, and complete win and reveal playtests.
Added offline Tower of Hanoi free play with 3–5 disks, complete legal-size enforcement, clear tower narration, reset, undo, keyboard controls, and full playtests at every size without timers, grades, or target move counts.
Added offline Peg Solitaire with English and European cross boards, complete orthogonal jump rules, legal-source and destination markers, natural no-move endings, move-back review, keyboard controls, and a full 31-jump one-peg playtest.
Added six guaranteed-solvable offline Sliding Tiles puzzles across 3×3 and 4×4 boards, with numbered and image-free symbol views, reset, undo, keyboard controls, and complete-puzzle playtests for every board.
Added three curated offline 8×8 Word Search puzzles with horizontal, vertical, diagonal, and reverse selection, found-word highlighting, reset, undo, keyboard controls, complete-puzzle playtests, and no child-entered text.
Added three fixed offline solo domino-chain puzzles with matching on either end, automatic orientation, mismatch feedback, reset, undo, keyboard controls, and complete playtests for every puzzle.
Added offline local two-player Backgammon with visible dice history, bar priority, hits, blocks, doubles, maximum-dice-use and higher-die rules, bearing off, undo, keyboard controls, and a 46-roll complete-match playtest.
Added offline local two-player Chess with check-safe legal moves, checkmate, stalemate, castling, en passant, four-piece promotion, the fifty-move draw, whole-move undo, keyboard controls, and short and 153-ply complete-match playtests.
Added three offline solo 6×6 fleet deduction puzzles with fixed clues, exact row and column totals, safe water filling, answer checking, undo, keyboard controls, and complete-puzzle playtests.
Added offline two-player Dots and Boxes with 2×2, 3×3, and 4×4 boards, box ownership, extra turns after closing a box, alternating starters, undo, keyboard controls, and a complete-match playtest.
Added offline two-player Nine Men’s Morris with placement, movement, flying, protected-mill removal, natural endings, whole-turn undo, keyboard controls, and a complete-match playtest.
Added offline two-player Kalah-style Mancala with narrated stone counts, extra turns, opposite-pit captures, end sweeping, undo, keyboard controls, and a complete-match playtest.
Added offline two-player Reversi with legal-move markers, eight-direction flipping, automatic passes, final disk counting, undo, keyboard controls, and a complete-match playtest.
Added offline two-player Connect Four with complete line detection, alternating starts, full-column handling, undo, keyboard controls, and a focused parent playtest prompt.
Added offline two-player Tic-tac-toe with alternating starts, undo, complete win and draw handling, keyboard controls, and a dedicated parent playtest prompt.
Added offline pass-and-play Checkers with required captures, chained jumps, kings, whole-turn undo, keyboard controls, and a documented path from basic board games to spatial variants.
Added an optional read-only family connection for availability, gentle guidance, sound, motion, and break reminders. Unconnected games make no request; connected games send no gameplay, progress, creations, or identity.
Expanded Starlight Crew to 25 freely selectable levels across five chapters, with visible difficulty labels, local completion marks, and balance checks.
Rebuilt DrawSprout with five specific guided projects, seven drawing tools, local saving, undo and redo, and collapsible navigation.
Go Fish now displays an explicit ask button for every rank in the player’s hand, with score, difficulty, and a turn log.
Corrected two invalid locked clues, added a regression check for every puzzle, and added optional completed-number highlighting and themes.
The build now reserves the public root for founder-signed Paint, Madison Row, and Sudoku releases while prototypes live under /demo/.
