## About Prefix Master

Two columns face off — prefixes on one side, root words on the other — and you pair them into real words like un + happy. Each correct match reveals the finished word and its meaning, such as 'unhappy — not happy', turning every level into a quick vocabulary lesson.

Prefix Master is a free word game that you can play instantly on FastPlayGames.com. No download or registration required — just click and play on any device.

## How to Play Prefix Master

Each level shows a handful of prefixes in one column and root words in the other. Tap a prefix, then tap the root word that forms a real word with it — for example 'un' plus 'happy' makes 'unhappy'. Every correct pair scores 25 points and displays the word with its meaning. Clear all the pairs to move on to the next level.

## Controls

Tap a prefix, then tap the root word it belongs with. A wrong pairing clears your selection so you can try a different one.

## Prefix Master Tips & Strategies

1. The prefixes are drawn from a fixed set: un-, re-, pre-, dis-, mis-, over-, and under-.
2. When unsure, read the result line — it shows the word forming as you pick.
3. Match the pairs you are confident about first to shrink the column.

## Frequently Asked Questions

### Does the game teach prefix meanings?

Yes. Each correct match shows the completed word and a short meaning, like 'rebuild — build again' or 'overlook — fail to notice'.

### How many levels are there?

Levels are endless. Each one draws a random subset of pairs (min(3 + level, 6), so 4 at level 1, capping at 6) from a pool of 30 prefix-root pairs, and the level counter keeps rising with no fixed end.
