Free browser games and Chrome extensions you can play right now, no download

DHSeaDev — Chrome Extensions, Windows Tools, & Idle Games

Every one of these runs straight in your browser or as a free Chrome extension — no download, no account, no ads. Most work fully offline once loaded. Here’s the current lineup, grouped by what kind of game they are.

Idle and incremental

Puzzle and strategy

  • Dino Dots — Dots and Boxes against a chain-strategy dinosaur AI, not a random-move bot.
  • Underglory — a hundred-level maze game where you grow a living vine instead of steering a cursor.
  • VEILFALL — a solo hidden-role deduction game with eight AI opponents that each hold real, separate hidden knowledge.

Arcade and action

  • Hot Dog Rush — a timed fast-food arcade game.
  • Prism Break — a canvas asteroids game with a shared global best score, playable free on the site itself.
  • Prism Cascade — a physics arcade game on the Chrome Web Store.
  • Bloom Rush — a plant-shop time-management game.

Something different

  • Lumenreel · Prism Crash — a slot-machine collectathon where the currency is time, not money.
  • TabCritters — thousands of procedurally generated critters to collect.
  • Emberkeep — a fire-spirit puzzle platformer built around a no-burn solvability rule.
  • Annoying Dino — an on-page dinosaur companion that just won’t leave you alone.

Everything above is built solo, shipped as MV3 Chrome extensions or browser-native pages, and free. The full, current list lives on the projects page; new ones get their own devlog post on /updates/ when they ship.
