You get a starting word, a target shape, and a hint. Example: CREAM +4, -3 _ _ _ _ _ _ "Morning beverage" ... did you guess COFFEE? You got this. Color clues guide you as you type: โข Green โ right letter, right spot โข Yellow โ right letter, wrong spot โข Red โ was in the starting word, but not the answer โข Gray โ not in the answer at all That's the whole game. No timers. No leaderboards. No notifications you didn't ask for. Just one puzzle a day, fewer letters than you'd think, and the satisfaction of seeing the word click into place.

The clearest difference is in-app purchases: diff at none against Grid Zen's 10. diff also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
