Drop discs into a real seven-column board; play a random, tactical or bounded-search bot, or share a local two-player match.
Useful to know
Does this game upload or automatically save my round?
No. The running board and moves stay in this browser tab. Optional completed personal best summaries require explicit opt-in; Snakes & Ladders and local matches never qualify. Saving starts off on each visit.
Can I use a keyboard and pause the game?
Yes. Use the focused board or labelled direction, roll and column controls. Pause or hiding the tab hides the board and stops active time. Return and choose Resume explicitly.
What are the current limits?
Classic 7×6 drops; three bot tiers; undo only in practice/local mode. Hard searches many moves ahead and spots threats on both sides; it is very hard to beat.
Do I need to fill in the settings before I can play?
No. Quick play starts a complete built-in round with sensible defaults. Open Customise this game only when you want to change the available settings.
Where are my files and inputs processed?
Play stays in this browser, with no account or remote leaderboard. Personal bests are saved only if you enable that option. Reset clears the round; use Erase device scores to remove those optional records from this browser. Private prompts and answers are excluded from the shared summary actions.
