Free browser games you can finish on a coffee break
Every game here loads in one tab, works with a keyboard or a thumb, and keeps your best score on your own device. No account, no install, no launcher. Below each game you get the part most game sites skip: how to actually get better at it.
Featured: 2048
Slide the tiles, merge equal numbers, keep your biggest tile in one corner.
Use the arrow keys, WASD, or swipe to start.
Keyboard: ← ↑ → ↓ or W A S D. Touch: swipe anywhere on the board.
Puzzle & logic
Slow games. You lose to your own bad planning, never to a bad frame rate.
2048
Merge matching tiles until one of them reads 2048. Easy to learn in ten seconds, hard to finish in ten tries.
💣Minesweeper
Read the numbers, flag the mines, clear the field. Three board sizes, with a first-click guarantee that never opens on a mine.
9×9Sudoku
A fresh grid every time, generated in your browser and guaranteed to have exactly one solution. Pencil marks included.
🧩Sliding puzzle
The classic 15-puzzle in 3×3, 4×4 and 5×5. Every shuffle is reachable, so the board you get is always solvable.
Arcade & reflex
Short runs, instant restarts. The kind of game that eats four minutes without asking.
Snake
Eat, grow, and run out of room. Four speeds, wrap-around walls as an option, and a best score that survives a page reload.
🧱Breakout
Bounce the ball, clear the wall, keep three lives alive. The paddle follows your mouse, your finger, or the arrow keys.
⚡Reaction time test
Five green lights, five clicks. Get your average, your median and your best in milliseconds — and a note on what that number means.
Memory & attention
Games that quietly measure how much you can hold in your head at once.
Two-player
Pass the device, or take on an opponent that never gets tired.

Why this site exists
Most "free games" pages are a thin wrapper around someone else's game, three redirects and a pop-up. Boss Games is the opposite bet: a small number of games, each written from scratch in plain HTML, CSS and JavaScript, with no third-party game frames and no login wall. If a game here feels slow, that is a bug we can fix, not a business model.
How the randomness works
Every shuffle, mine placement and tile spawn comes from your browser's cryptographic random number generator, drawn through a rejection loop so that no value is slightly more likely than its neighbours. It is more care than a card game needs, and it means a bad run really was luck.
Your scores stay yours
Best scores, times and preferences live in your browser's local storage on your own device. There is no account to create and no score to upload, which also means clearing your browser data clears your records. Full detail is in the privacy policy.
