Verified round model
How a round of Smartle works.
Objective, input, feedback and stopping condition checked 3 October 2026.
Objective
Build a valid five-letter word in every horizontal row of the grid.
Your move
Drag one letter onto another letter anywhere on the board to swap their positions.
What changes
Valid word rows turn green; the swap counter and solved-row progress update after moves.
Round end
The daily board is solved when all five horizontal rows form valid words.
Why it stands out
A green row can still supply letters for the rest.
Smartle permits multiple solutions from the same letter set. Solving one row is useful feedback, but preserving it can be less important than redistributing letters across all five rows.
Best for
- Solvers who prefer multiple valid answers to one hidden word.
- Players who enjoy rearranging letters under board constraints.
Think twice if
- Players who want a puzzle without English vocabulary requirements.
Five words from one shared letter set
Smartle presents 25 letters in a five-by-five grid. Drag a letter onto any other tile to swap their positions. The goal is to form a valid five-letter word in each horizontal row. You are not trying to recover one predetermined answer set: the official rules allow multiple solutions.
A valid row turns green. That does not lock its letters. If the remaining rows need a letter from a completed word, you can break that word and rebuild it later. Treat the whole board as one pool of letters rather than finishing each row permanently in sequence.
From the studio
In his September 29 submission, Pavlo Yakubovskyi describes Smartle as a shared daily letter grid that ends when all five rows are solved. He identifies Pro Mobile as a small independent studio in the Netherlands and notes that Smartle also has iOS and Android apps. The studio location is creator-supplied; this check covers the browser game, not the apps.
Use row feedback without getting trapped
After making a word, inspect which vowels and repeated letters remain outside it. A completed row can consume letters that make the rest of the board awkward. Try another word arrangement before spending many swaps on an impossible-looking leftover row.
The browser check formed RATER with one swap. The row turned green, the swap count increased to one and the progress bar advanced. The other four rows were not solved. The official rules describe Sprint and Archive modes, but their access and limits were not tested.
The free daily board was available without an account. Advertising slots were visible around the web game; they did not block the checked interaction. Pro Mobile is credited on the official site. This guide does not extend web observations to the optional mobile apps.
How to play
- Start the Daily board in the browser.
- Drag a letter onto another tile to exchange their positions.
- Use green rows to identify valid five-letter words.

The evidence behind this page.
One drag swap formed RATER. That row turned green, the swap counter became 1, and solved-row progress advanced. Desktop browser only; full daily completion, mobile play and reset boundaries were not tested. The listing uses a direct official link, not an embedded game.
