All games should have the option to have the timer turned off.
I regularly do cryptic crosswords (so this sort of game is in my wheelhouse). My goal is to complete the puzzle, not do so in a particular time. Completing it is often hard (depending on which paper I've picked up). There is no timer when I'm say with paper and pen, so it baffles me that every online newspaper cryptic has a timer on by default, and in some cases it can't be disabled.
It's also the thing that "ruined" the LinkedIn puzzles for me. They're generally fun puzzles, but timing it against my PB or - worse - people I'm connected to on LinkedIn just wrecks the experience. I opted out of leaderboards, because I don't really want to know a guy I worked with years ago trashes me at Queens every morning.
Strong agreement that a "relax" mode is needed here - at longer word lengths its becoming a test of recall and anagram ability, and that's fun in its own right. The timer just makes it a bit "meh", and I won't be returning as a result. Shame.
