Changelog

Kids accounts: when signing up, choose “For my child”, pick a nickname and an animal avatar. The kids version opens only when the child signs in with that account.

Adventure map with 10 levels across Sunny Meadow (3×3), Ocean Bay (4×4) and Star Mountain (5×5), including countdown levels. Each finished board earns 1–3 stars and opens the next level.

Free play on 3×3, 4×4 or 5×5, counting up or down, plus a sticker book with 12 stickers to collect and personal best times.

A new public page at /kids for parents: explains how the kids version works, how to create a kids account and how children's data is handled — also linked from the site footer under “For Kids”.

Ollie the owl cheers along, with playful sounds (can be muted), big colourful tiles and a celebration after every board.

Grown-ups zone behind a parent check: see today's and this week's activity, change the nickname or avatar, change the password, sign out or delete the account.

Kids accounts have no AI Coach and their results are never mixed into the community comparison of adult players.

The Privacy Policy now has a dedicated section on kids accounts: we store only a nickname, an avatar and game results — no real name, no ads.

Game time is now measured precisely (to 0.01 s) from your first to your last correct click — the celebration animation no longer adds to your time.

Wrong clicks are counted for every game and shown in your history, Dashboard and session summary. The AI Coach uses them too.

Colour sessions now actually play the Colour grid, and you can pick Classic or Colour when setting up a session.

Counting down in Colour mode no longer asks for two red numbers in a row, and the Divergent variant counts black in the opposite direction as intended.

When time runs out, the game now records how many numbers you actually found (also in descending and Colour games).

Time limits for large grids were raised based on real player data: 6×6 / 7×7 are now 90 s / 150 s in Classic and 120 s / 180 s in Colour.

The Dashboard loads your complete history (no 1,000-game cap), counts only completed games for best and average times, separates Classic from Colour, and uses your local date for streaks.

Games played offline are kept on your device and synced automatically when you are back online — never twice.

Sign in with Google, reset a forgotten password, and permanently delete your account and all its data from Settings.

The AI Coach is now available only to signed-in players, with a fair daily message limit, and compares you with players of the same game type.

Better accessibility: grid cells announce their number and colour to screen readers, and confetti respects the reduced-motion setting.

Colour Schulte Grid now records search times between correct clicks across all variants (single-focus, alternating, divergent) — previously colour-mode games saved no timing data, leaving colour-only users without micro-analytics in the Dashboard and AI Coach.

AI Coach now receives full per-number timing metrics (consistency, pacing, fatigue patterns, stuck moments) for Colour mode sessions, matching the depth of analysis previously available only for Classic mode.

Dashboard now includes a 7×7 grid filter tab — search-time heatmaps, KPIs and history for 7×7 sessions are no longer hidden from view.

Zen mode now activates on the first game: an async settings sync was prematurely resetting the active-game state right after the first click, leaving the top and bottom bars visible. The reset effect now only fires on real training-mode changes, so the navigation hides immediately on the first interaction as intended.

Zen mode layout: bottom navigation no longer breaks on first activation during a game — the action button and content area now animate smoothly (300ms) in sync with the disappearing navigation, with no empty gap at the bottom

AI Coach session review is mode-aware: after finishing a Session, the AI explicitly recognizes Classic vs Colour mode, stops mixing lifetime averages across modes, and never judges Colour-mode times against Classic benchmarks

AI Coach chat (bottom drawer) parity: free-form chat now also splits stats by mode — per-game mode label in recent games, separate personal bests and averages for Classic vs Colour, percentiles cited only against Classic data, with an explicit caveat for Colour

No-op filter: AI Coach no longer suggests enabling settings that are already active — server-side deterministic filter checks your current settings before sending suggestions

Proactive Session Mode recommendations: AI Coach suggests structured Session Mode when you have 15+ games, >75% success rate, and a daily training habit (3+ games/day)

Proactive Colour Mode recommendations: AI Coach suggests Colour Mode when you hit a plateau (10 games without improvement), show high consistency, or have played only Classic mode for 20+ games
