Play Dropsum online for free

Using the mouse, drop tiles into the grid. Try to make adjacent tiles (columns or rows) add up to the required value. When you do, the tiles in that group change color, until eventually some will turn red. Make a group with a red tile and it will explode, causing the tiles above to drop down, leading to combos and big points!

Dropsum is available on GameBig as a browser game. You can launch it when you are ready (use the green Play button below so the game only loads after you choose to play, which keeps the first view of this page lighter for visitors on slower connections).

Our editors describe each title with the official short description when provided, list the default controls, and link related games so you can discover more in the same genre. If you need help with account issues, removals, or partnerships, use the contact page so we can respond by email.

Tips for a smoother session

  • Close unused tabs and pause large downloads so the browser has free CPU for Dropsum.
  • Use fullscreen when supported for a stable aspect ratio and fewer accidental clicks outside the frame.
  • If audio is blocked, interact once with the page (Play counts) so autoplay policies can unlock sound where the developer allows it.
  • Bookmark this URL if you plan to return; the same page will list updated play counts and community rating over time.

No app store install is required for typical HTML5 games. Flash-era titles may use in-browser emulation (Ruffle) when marked as SWF.
