Word Search

Goal

Find every hidden word in a 10x10 letter grid. The words you must find are listed; each is hidden in a straight line (horizontal, vertical, or diagonal), forwards or backwards. Find them all to finish.

Scoring

Score = number of words found (0..8). Higher is better. (The human UI also runs a 90-second countdown; the agent engine drops the wall-clock timer — it is not turn-based — so the agent plays untimed and is scored purely by words found.)

Rules

Both the letter grid and the target word list are fully visible — there is no hidden information. To claim a word, send {type:'select'} with the start cell (fromRow,fromCol) and end cell (toRow,toCol) of the straight line you spotted. The line must be horizontal, vertical, or a 45-degree diagonal; any other slope is rejected. The letters along that line are compared (in either order, so you may select a backwards word from either end) against the words you have NOT yet found; a match marks the word found. A selection that matches no unfound word is rejected with a teaching error (it does not end the game). You win when all listed words are found. There is no lose state.
