Find words in the letter grid before time runs out!
Boggle is the classic word-finding game. You get a grid of letters and a countdown, and you find as many words as you can by tracing paths through touching letters. Letters connect horizontally, vertically and diagonally, so every letter has up to eight neighbours, and no single letter may be reused inside one word. It has been a family game since the early 1970s, and it has survived because the rules take fifteen seconds to learn and the skill ceiling is effectively bottomless.
What makes it different from a word search or a crossword is that nobody hid the words. There is no answer key. A grid of sixteen letters typically contains a few hundred valid words, and the gap between a casual player and a strong one is not vocabulary so much as search technique. A good player is not recalling more words; they are looking at the board in a way that surfaces words faster.
Standard Boggle scoring rewards length steeply rather than linearly: three and four letter words score 1 point, five letters 2, six letters 3, seven letters 5, and eight or more 11. The practical consequence is that one eight-letter word is worth about as much as eleven three-letter words, so a round spent hunting long words usually beats a round spent farming CAT, RAT and TAR. Short words are still worth taking when you spot them for free, but they are not a strategy.
Hunt suffixes, not words. The fastest way to multiply a score is to find one stem and then run endings through it. If you find PLANT, check PLANTS and PLANTED. If you find CARE, check CARES, CARED and CARER. Trained players scan for the tiles that make ER, ED, ES, ING and LY sit next to each other, then look for stems that can reach them, because that turns a single discovery into four or five entries.
Work outward from rare letters. Common letters appear in almost everything, so they give you no direction. If the grid has a J, K, V, W or Z, start there. Those letters sit in far fewer words, which means the search space around them is small enough to exhaust quickly, and words containing them tend to be longer and therefore worth more.
Learn the shape of your own grid. Corner tiles have three neighbours and centre tiles have eight, so long words almost always run through the middle. If you are hunting a seven-letter word, it will very likely pass through a central tile. Conversely, a promising letter stuck in a corner next to three unhelpful neighbours is usually a dead end, and recognising that in one glance saves you ten seconds.
Sweep systematically, then freely. Give the first part of the round to a deliberate pass, tile by tile, asking what two and three letter openings each tile allows. Spend the rest of the round on free association. Starting with free association feels faster but tends to circle the same three obvious words while the rest of the board goes unexamined.
