Thanks for the helpful input on this. Concerning the zen mode constraint, do you feel like the countdown timer is what's feeling off-putting to you, or is it the combo reset on shuffling?

Many players who love this mode are also fans of blitz chess. Curious if you're into rapid/bullet modes in general or that's not really your cup of tea.

Not happy about it too. but the trick is to refresh the page and press shuffle to get a new puzzle. ;)

I see no shuffle button, at least not on mobile, refreshing didn’t help.

Edit: ah, you mean in zen mode - true, it’s there. Then again, the timer is still running, which I find annoying.
