Bigram

About Bigram

Bigram is a small browser game on Optimal Fun, the site that also hosts a game called Nuudge. Its board is two empty rows above a pool of seven dark tiles, each holding a pair of letters. Some tiles start the wrong way round: tapping or clicking one reverses it, so UA becomes AU. You drag tiles into the rows in any order to build words.

The puzzle is built around two hidden words of even length, often one short and one long, but the game does not insist on its own answer. It checks both rows against the NWL2023 word list, and any two valid words that together use all seven tiles solve it. Shuffle mixes the remaining pool, and Recall sends every tile back from the rows.

If you are stuck, Need a hint locks every tile in its correct orientation, flipping the reversed ones into place; it cannot be undone, and the reverse rule is struck out of the instructions. A Yesterday's answer link shows the previous day's two words. When you solve the puzzle, the game shows your time, which pauses while the tab is hidden, and your streak, kept in your browser, and offers a Share button.

A new set of tiles appears at midnight on your own calendar day, the same set for every player, taken from a fixed schedule that began on 25 September 2026. The game is free, with no account and no ads seen on the page.

How to play Bigram

1. Open Bigram; today's seven two-letter tiles sit in the pool under two empty rows.
2. Drag tiles into the rows to start building two words, in any order.
3. Tap or click a tile to reverse its two letters when it reads the wrong way.
4. Use every tile; when both rows spell valid words, the puzzle is solved and shows your time and streak.
5. Stuck? Need a hint locks all tiles the right way round, and Yesterday's answer shows the previous day's words.

Tips

• Look for awkward pairs first, such as a double letter or a J, Q or Z: they usually sit at a word's start or end, which narrows where they go.
• Read every tile both ways; a pair that looks useless forwards often becomes a common ending like ER or ED when reversed.
• Any two real words win, so if the intended long word will not come, try splitting the tiles differently between the rows.
• Save the hint for last: once used it cannot be undone, though hint-assisted solves still count for your streak.
