Quintext vs LuXOR

Quintext is a free daily word puzzle. Each level is a 5x5 grid starting with some letters filled in. Your goal: complete the grid so all rows and columns make valid 5-letter words, crossword style. The words will be the same horizontally and vertically. Each puzzle has a unique solution. While playing, you see real-time feedback about which rows and columns have valid words or parts of words. If you get stuck, tap the buttons to reveal additional letters or show all dictionary words which fit in the current row or column. In addition to the free daily puzzles, a one-time in-app purchase unlocks a library of over 50k additional puzzles with a wide range of difficulty settings. These are available offline for the lifetime of the app and can be shared with other players who have unlocked the library. For colorblind players, this app responds to the system-wide Differentiate Without Color setting.

Turn out every light. LuXOR is a simple puzzle with a deep twist. Tap a light and it flips, along with its neighbors above, below, and to each side. Your goal is to switch the whole board dark. It sounds easy. Then the third tap undoes your first one, and you start to think. Every puzzle has a par. Solve it at par or better to earn all three stars, or come back later and chase a cleaner solution. There’s no timer and no rush. Just you, the board, and that satisfying moment when the last light goes out.

Lux is Latin for light. XOR is the logic behind every tap: press a light once and it flips, press it twice and it’s back where it started. Once you see it that way, the puzzles start to open up. LuXOR is free to play and supported by ads. Prefer it quiet? A one-time in-app purchase removes the ads for good. Made by one developer at BluMonkey Software, who still gets a kick out of the last light going dark.
