Online multiplayer is here — create a room, share the code, and play together.
Multiplayer Games — Play Free Online with Friends
Nine games with a real opponent behind the screen instead of just a CPU. Tic Tac Toe, Checkers, Dots & Boxes, Color Cards, Chip Line, Connect Four, Reversi, and Paint Battle all support genuine real-time online play — create a room, send the code or link to a friend on a completely different device, and the match starts the moment they join, with no download or account on either end. Rocket Knockout rounds out the list with local same-device 2-player instead of online — split the keyboard and duel a friend sitting next to you in its shrinking-arena physics battle. Every one of the eight online games also still supports its original solo-vs-CPU and same-device pass-and-play modes underneath, so a room is something you open when you want it, not something you're forced into.
Choose a game for your next session
For a friend on another device, use Create Room and send the room link or code, then wait for that friend to join. Quick Match prepares a computer opponent; it is not evidence that another person is online. A local two-player option, where offered, uses the same device. Connect Four, Checkers and Tic Tac Toe are useful starting points because turns are easy to follow. Both players need a connection for an online room.
Three places to start
Connect Four
Take a winning drop if you have one; otherwise check whether the opponent can win on the next turn.
Checkers
Jumps are mandatory in both rulesets, and once a piece starts capturing it must keep chaining hops as long as another capture is available — plan a move knowing you can't stop partway through a multi-jump
Tic Tac Toe
On the classic 3x3 board against the AI, the opponent runs a full minimax search and is mathematically unbeatable — the realistic goal is forcing a draw, which starts with taking the center or a corner on your opening move.
Connect Four
Line up four discs before the CPU beats you to it.
Players who want to practice checking landing squares and building threats on a standard 7-column, 6-row board.
Color Cards
Match colors and numbers to empty your hand first vs 3 CPUs.
People who want a full 3D table with up to nine CPU seats to fill, or two friends who just want to open a room and play without installing anything.
Tic Tac Toe
Take on an unbeatable AI or a friend on the couch.
Best for quick rematches between other tabs — the scoreboard tracks wins and draws across as many rounds as you want, and the bigger boards give players who find 3×3 too solved something with actual fork-setup room.
Checkers
Outmaneuver a minimax CPU with Classic or International rules, in 2D or 3D.
Suits players who want a real strategic opponent rather than a time-killer — mandatory jumps mean careless moves get punished immediately, which rewards someone willing to think a few captures ahead.
Chip Line
Play a card, place a chip, and line up 5 in a row to win.
For players who want card choices combined with a five-in-a-row board goal, against CPUs or friends on separate devices.
Dots & Boxes
Claim more boxes than the CPU on a 4×4 grid.
Suits players who like a slower strategic board game with real depth, whether solving it solo against the CPU or working the same tactics against a friend.
Reversi
Flank your opponent’s discs to flip the board to your color.
Fits players who enjoy a fixed classic ruleset with real depth to optimize, whether that is a solo session against the CPU or a longer back-and-forth match with another person.
Rocket Knockout
Blast, ram and ring out the other rocket in a tiny asteroid arena.
Works best as a short, high-intensity couch session with a second player, or a few solo rounds against a CPU tier that actually matches your skill.
Paint Battle
Spray territory, dodge your rival, and hold the highest paint percentage when the 90-second clock runs out.
Suits players who like an arena shooter but get more satisfaction from board-control math than from kill counts — a good fit for a tense 90-second session rather than a long grind.
