Wreflecto Mirror
Fill a mirrored word square where every row is also a column.
Every day: One symmetrical word square a day, the same for everyone, with its first row and column given: fill it so every row, and so every column, is a valid word. New puzzle: Midnight on your own device's clock (the countdown to the next game runs to local midnight).

Wreflecto Mirror is a daily word square. The first row and column are filled in, and every letter you type at one cell also appears at its mirror cell across the diagonal, so each row you complete is also a column. Fill the whole square with valid, different words as fast as you can.
About Wreflecto Mirror
Wreflecto Mirror, from Nowflux Labs, is built on the old word square: a grid where the words read the same across and down. Each day you get a square with the first row and first column already in place, and you fill in the rest. Because the square is symmetrical, typing a letter at row 2, column 4 also writes it at row 4, column 2, shown by a dashed border on the mirror cell.
Every row has to be a valid word, and duplicates are not allowed. When you complete a row, a check mark or a red X tells you whether it works. You move with the arrow keys or by clicking, and switch typing direction with a double click or the shift key. A timer runs while you play, and when you finish the game shows its own suggested solution, your time and your stats, including win rate and streaks.
A new square arrives each day at local midnight. A paid tier adds unlimited puzzles and the archive of past dailies. There is also a paid iOS app from the same maker that carries the Mirror daily alongside a second mode, Cross, with 4x4 and 5x5 grids and offline play. It suits players who like crossword construction and puzzles such as Waffle or Knotwords.
How to play Wreflecto Mirror
- Look at the given first row and column.
- Click a cell and type; the letter also fills its mirror cell across the diagonal.
- Complete each row so it forms a valid word; a check mark confirms it.
- Fix any row marked with a red X, including duplicates.
- Fill the whole square, then compare with the suggested solution.
Tips
- Fill the second row first: it fixes the second column and narrows everything else.
- Common endings such as -ED, -ER and -ES are useful in the last column and row.
- If a row will not work, change a letter in the column that crosses it.
