I would argue that “Casual Games” are games that you can pick up any time and start playing. There's no need to save progress etc., because you only want to start a new game when you start one anyway (think Solitaire or Minesweeper). Hybrid-casual, I would argue means games that are sort of casual, but you actually do store some sort of progress (level, points, coins etc), but the gameplay itself is always the same and you don't store which level (i.e. scene, not stats) you were on when you quit.
That's a nice definition i think. Sounds like the missing piece i never really understood regarding that ‘casual’ term.
Though, some relaxation is probably needed. The best casual game to me is Zuma, but like a jump'n'run this uses manually designed levels. And you won't play them all in row, so saving progress is needed.
So i would remove this, and reduce it to accessible games with simple, ideally self explaining and addictive mechanics.
Bolt on features like customization, collectibles, items, social stuff, leaderboards etc. depends on saved state and progress as well. Likely they can give the player advantages, but should not directly effect the mechanics to remain casual.
