Crossword Jam Level 399 sits in Israel and holds 17 words, the longest answer being OPENLY at 6 letters. That is a substantial board, enough that checking off what you already have is faster than re-reading the whole list.

Every answer below carries its letter count, which is the fastest way to match an empty slot: counting the squares in a gap and scanning for that exact length beats reading the list from the top. Answers are listed in the order the game accepts them, so the page reads the way the level plays.

6 of the 17 answers run to three letters or fewer, which is where levels like this are usually lost. The long answers go in quickly; it is the short ones filling the gaps between them that get missed, because they are easy to read straight past.

This level sits in the 301–400 block, with level 398 and level 400 linked at the foot of the page.

How to play

How Crossword Jam Works

The same three moves solve most Crossword Jam puzzles, including this one.

1

Place the longest word

It uses the whole set and anchors the grid, fixing crossings that narrow everything else.

2

Count the empty run

A three-square gap has very few candidates. Match by length before thinking about meaning.

3

Reuse what you placed

Short answers are usually fragments of the long one. Look at what you have already solved rather than at the tiles.

Crossword Jam Tips & Strategy

Starting with what this particular level teaches you.

1

This chain has 17 links

Fill the answers you are sure of first — each confirmed link constrains its neighbours far more than the clue alone.

2

Longest answer is OPENLY

At 6 letters it is the most constrained slot on the level, which usually makes it the easiest to place.

3

The long answer is the letter set

Every other word is built from its letters. That single fact discards most candidates without looking at the board.

4

Short words finish levels

The long answers come easily; the three-letter fillers threaded between them are what stall a grid, because they are easy to read past.

5

Test the endings

S, ED, ER and ING turn one solved answer into two or three more. It is the quickest way to unstick a board.

6

Build from the rare letter

A J, Q, X, V or Z narrows the field faster than any vowel. Work out where it can go first.
