Arkadium's Fill Ins

Fill Ins is one of Arkadium's word games, played free in the browser on arkadium.com with ads, and also carried on game portals such as azgames.io under the name Daily Fill Ins. Its own how-to screen sums it up: it is like a crossword, but the words are given instead of clues, and the goal is to fit them all into the grid.

Each puzzle is a 15 by 15 crossword-shaped grid with a list of words beside it, split into Across and Down. Every word in the list fits somewhere, and the only question is where. You start from a word whose length matches just one slot, place it, and its letters then decide which words can cross it. One letter is already filled in to get you going.

The game opens on a calendar of the current month. Each day is a card with its difficulty in one to three stars and a Play button, and the days already past in the month can still be played, so a missed day is not lost; days still to come stay greyed out. A monthly score adds up the points of the puzzles you solve, and the day's own puzzle is worth a 50 point daily bonus. You can also step back to earlier months.

Above the grid sit a timer, undo and redo, a check button, a reveal button and a print button, and the settings let you hide the timer or turn the helpers off. No account is needed to play, and the Arkadium page keeps a leaderboard for the game.

It suits crossword players who enjoy filling a grid but want a puzzle that is all fitting and deduction, without needing to know the answers to clues.
