v0.48.0 - 4/20/2021 - 7/27/2021

  • added an in-game timer, can be shown via the gear icon
    • timer is just your own time spent within that puzzle and does not show or count other people

v0.44.0 - v0.47.0, ~ 4/20/2021 - 7/10/2021

v0.32.0 8/27/2020

An entirely new design for browsing our image catalog!

  • Individual image pages
    • Linkable! You can now link an image to your friends for some pre-puzzle discussion!
    • Credits the photographer (in the case of photography put into the public domain)
    • Shows related images
  • Shows portait and landscape images (previous catalog cropped all previews to a misleading square shape)
  • Mobile/Tablet/Desktop compatible - the catalog has been made for a variety of screen sizes
  • No longer requires sign-in just to browse (though sign-in is still required to actually create a puzzle)
  • Requires drastically less bandwidth to browse (various image and pagination optimizations)
  • Coming later: better tags, image descriptions

v0.30.0 6/10/2020

  • Can now interact with pieces *through* the chat interface
  • Pasting a link to another puzzle in-game produces a clickable link for the other players
  • Chat occupies less screen space, and can be hidden entirely
  • 'Hosted' games are now marked on the front page

v0.29.0 6/6/2020

Chat system and a new anti-troll mode initially rolled out to user-created games (not the themed or chaos lobbies).

  • New chat system
    • Press enter to start typing, and enter again to send
    • Colorized usernames
    • Text lasts much longer before fading away
    • Pressing enter after text has faded away shows the chat again
    • Per-person mute feature removes a username and all their messages from the chat
    • People joining the game are announced by the server in the chat, among other things
  • Hosted mode
    • A new *public* game mode where the person who starts a puzzle gains the power to kick/ban players. This is like the current public games but with some ability to fend off trolls.
    • This mode is member-only (everyone must be signed-in to play).
    • Kick: disconnects a player from a game, but allows them to rejoin
    • Ban: disconnects a player from a game, and prevents them from rejoining
  • Player List
    • A new button has been added to the interface that shows the player list
    • Everyone currently connected can be seen in the player list
    • Various moderation opions exist in the player list
  • Scores for members are now saved long-term along with the puzzles, instead of being session only (only for the game modes receiing this patch, for now)
  • Scoring has been removed for anon players (no deliberate reason for this... just a side effect of how things work now).

v0.28.0 5/4/2020

  • private puzzles are limited to 10 players
  • fixed a bug where the wrong private game could be joined via create/resume/reconnect (is this is the last of this bug? we shall see)

v0.27.0 4/29/2020

  • user-initiated public games are back!
  • fixed two bugs where players attempting to continue or start a new private game could be placed into an existing private game

v0.26.0 4/21/2020

  • improved sign in, all devices should now stay signed in properly
  • decreased the chance of puzzles getting lost/bugged during traffic spikes
  • fixed an intermittent bug where players were all being sent to the same server when trying to create a new puzzle

v0.24.0 4/18/2020

Mostly bug fixes for problems found by players (thank you!), and server improvements.

  • now running 650+ game lobbies
  • added ~40 more images, many picked by players
  • tweaked ad frequency (less, overall)
  • created some new themed puzzle playlists for the front page
  • fixed a bug where a player who refreshes the page right as they join could enter the game twice and would not be able to move any pieces
  • fixed a bug where a game server would fail to clear the board before loading a new puzzle, and then would present the players with two (or more) puzzles worth of a pieces
  • fixed a whole bunch of very weird ghost piece / can't move piece / extra piece / extra player hand bugs related to the above
  • fixed a bug related to traffic spikes where certain servers were not being returned to the pool of available lobbies
  • bug found: during traffic spikes a small (less than 1%) number of puzzles were failing to save. Game lobbies will now repeatedly try to save puzzles if they ever encounter a failure (we won't know if this works until more time has passed).
  • bug found: during traffic spikes there is a very small chance that a newly created puzzle will not be added to the "My Puzzles" page. There is no fix for this yet -- but if it happens to you, the puzzle can be recovered by going into your browser history and rejoining it.


  • login now lasts 36 hours (instead of instantly ending when closing the browser)
  • improved image loading speed
  • added more private game lobbies


  • added 300+ more game lobbies
  • created new playlists for the themed lobbies
  • added scoring to chaos and themed games
  • added video preroll advertisements at a maximum rate of one per 15 minutes
  • NOTE: we'd like to offer an ad-free premium version JigsawPuzzles.io in the future with some additional gameplay value (for now we just need to pay some server bills!)

v0.19.0 3/24/2020

  • "username has joined" appears when someone joins a game
  • player hand-cursors are now visible immediately when they join (previous only visible after touching a piece)
  • Scoring: scores are now visible in the top right
  • Scoring: players get a point when they lock a piece to the board
  • Scoring: hide the scores by clicking the 'Scores' button
  • NOTE: this patch will role out gradually and will not be on all servers immediately
  • Infrastrucutre: added 200+ private lobbies over the previous few days
  • Catalog: added 400+ images over the the previous few months (so many that we need to make a new catalog / interface in the near future)
