Free puzzle games
Free puzzle games are the titles on Cardboard Arcade that run in your browser and cost nothing to play, and the puzzle section currently holds 14 of them, each on its own page, from classic jigsaw sets to hexagon shape fits. Every one of the 14 loads in about 5 seconds, runs on a standard browser with no download, no account and no app, and the last full inventory of the section was updated on 31 August 2026. The rest of this page lists all 14, explains how the browser play model works, and sorts the set for the specific ways people usually want to play.

The full set is the 14 titles on the puzzle section of Cardboard Arcade, and they group into 5 families: jigsaw and picture assembly, tile and block sliding, word play, number logic, and shape fits. The word and number families overlap with other sections of the site, so they cross over into the adjacent lists below, while the jigsaw, block, sliding and shape-fit games are puzzle-only and make up the heart of the section.
Free block puzzle games
The block family on the section is the largest single group, with 4 games built around filling a grid with moving pieces. They differ in the pieces they give you and in the grid they fill them into, and together they cover the 3 main mechanics that define a block game: sliding a tray of pieces, rotating pieces on a board, and packing irregular shapes into a fixed frame.
- Block Drop: a 10 by 10 grid where 2 to 4 block pieces fall from the top and you slide and rotate them before they lock in place, clearing a line when a row or a column fills completely.
- Pentapiece: 5 pentomino shapes at a time on a 6 by 10 board, and the win condition is to place all 12 pentominoes so the board is exactly full with no gaps.
- 15 Puzzle: the classic numbered tile grid of 16 squares with 15 numbered tiles and 1 empty square, where the goal is to reach 1 to 15 in order by sliding tiles into the gap.
- Hex Fit: a hexagon board of 37 cells, where you place the 12 hexagonal polyominoes so every cell is covered, one of the two shape-fit games in the section.
Free crossword games
The word side of the section is represented by 3 crossword titles, which is fewer than the block family because most word games sit on the separate word section. Cardboard Arcade keeps them on the puzzle list too, since a crossword is a logic puzzle in grid form, and the 3 differ in how the grid is built and how the clues are written.
- Daily Crossword: a 15 by 15 grid with 80 across and down clues, generated fresh every day at midnight UTC, with a timer and a 10 minute hint per grid.
- Word Search: a 12 by 12 grid hiding 30 words, where you trace a word in any of the 8 directions, including diagonals and backwards.
- Sudoku: a 9 by 9 number grid with 17 pre-filled clues at the easiest setting, rising to 26 at the hardest, where each row, column and 3 by 3 box must hold the digits 1 to 9 exactly once.
Jigsaw puzzle games free online
The jigsaw games are the picture assembly titles, and there are 4 of them, which makes this family the second largest in the section. A jigsaw here means a photograph or an illustration cut into pieces that you reassemble, and the 4 differ in piece count, cut style and whether the outline is visible.
| Title | Piece counts | Board | Extra |
|---|---|---|---|
| Jigsaw Classic | 50, 100, 300 | 12 by 8 | Optional preview thumbnail |
| Christmas Jigsaw | 25, 50, 100 | 10 by 10 | 20 festive pictures, new set each December |
| Seamless Jigsaw | 64, 144, 400 | 16 by 16 | No visible outline, pieces are cut with irregular seams |
| Photo Jigsaw | 49, 121 | 7 by 7 or 11 by 11 | You upload your own picture, stored only in your browser |
The Christmas Jigsaw set is the seasonal one, with 20 pictures that rotate through the December titles, and the Photo Jigsaw is the only one that uses your own image rather than a built in photograph.
Puzzle games free online no download
The no download point is the whole design of Cardboard Arcade, and it applies to all 14 puzzle titles in the same way. When you open a title, the game loads as 3 files, a page of about 40 kilobytes, a script of about 180 kilobytes and a small sprite sheet, and the browser runs it directly. There is no installer, no account, and nothing written to disk, so the same page works on a windows or mac computer, a laptop, or a phone, in any current browser.
- Runs on windows, mac and android, in Chrome, Edge, Firefox and Safari, with no version of the game to install or update.
- Needs no download and no app, so a title you find on the site is the same one you play, and the load finishes in about 5 seconds on a typical home connection.
- Works offline once loaded, because the files are cached by the browser, which is close enough to an offline game for a second play through on a dead wifi connection.
- Has no ads inside the play area, so a puzzle you are concentrating on is not interrupted by a banner or a countdown.
Because the games are pure browser files rather than a native app, the android version of a title is the same page you open on a desktop, which is why there is nothing to download to a phone and no separate mobile build to keep in sync.
Puzzle games free online for adults
The set is built for adults because none of the 14 is aimed at a young child, and the difficulty in each one comes from logic and patience rather than from time pressure or flashing screens. The same 14 games serve as a full session for an adult, and the way they fit an adult play style is this:
- Sudoku and the Daily Crossword give a single 20 to 40 minute session with a clear end state and no wrong turn that is unrecoverable.
- The 300 and 400 piece jigsaw games are the long form option, a 1 to 2 hour session that rewards setting aside one region at a time.
- The block and hexagon games are the short form, a 5 minute puzzle that is either solved or reset, which suits a break between tasks.
- There is no account and no leaderboard, so progress is private and a game is as hard or as easy as the setting you pick.
The word games carry the most text on screen, so they are the natural pick if you want a puzzle that reads like a page rather than a picture, and the hexagon and pentomino games are the purest logic ones, with no theme and no story, only the shapes.
What to play with friends
Playing a puzzle with friends on Cardboard Arcade means sharing one screen or one session, since the 14 titles are single player by design and there is no multiplayer server. The 2 workable setups are a shared screen, where you take turns on one device, and a side by side race, where each person opens the same title on their own device and tries to finish first.
- Shared screen: one laptop or a phone passed between 2 people, good for the 5 minute block and hexagon games where a turn is a single move.
- Race: the same title open on 2 devices, best on Sudoku and the Daily Crossword, because both start from the same grid and finish at the same number of filled cells.
- Pair puzzle: one person handles the edges of a jigsaw and the other handles the centre, which works best on the 100 and 300 piece sets where there is enough to divide.
For a two person game on a single device, the 15 Puzzle and the pentomino games are the most turn friendly, because a move is one clear action and the board state is easy to read across a shared screen.
