Playable Demos
No download, no account. Play Tic-Tac-Toe against a real AI opponent right on this page. The other two give you a preview of what full chat adds.
Classic 3-in-a-row against an AI that switches up who goes first, tries to win, and comments on the result in character. Plays best-of-many while you keep it open.
Rock, paper, scissors — but from round three onward the AI starts reading your patterns. The in-chat version also adds voice-reactions after every round.
Classic 20 Questions, two ways: the AI thinks of something and you narrow it down yes/no, or flip it and let the AI try to guess what's in your head in twenty questions or fewer.
All AI Games
Games are built into the chat experience. Pick a character, open the game panel, and play — the chat continues alongside the board.
Three in a row against an AI that can win, block, or play a little loose if you're having a bad day. First on the page above.
Try in chat →Best of five. Pattern reader engages on round three. Your AI companion chirps at you between rounds, win or lose.
Try in chat →Pick a category, start asking. Or flip the roles and make the AI guess what you're thinking. One credit per AI turn.
Try in chat →An emoji combo, a short window, and three guesses. Movies, songs, idioms, food — two thousand puzzles in the deck.
Try in chat →Pick A or B. Your AI companion reacts to your choice, pushes back, or confesses the same weird preference.
Try in chat →How It Works
Games and chat are not two separate apps. Open a game inside a chat and the character you picked shows up on both sides of the screen.
Most online games are either grinding against a faceless matchmaker or wrangling friends for a schedule. AI games on HeyAIBuddy sit in a third lane: quick to start, never empty-server, and the opponent is someone you actually want to talk to afterwards. The games are short on purpose — three minutes of Rock Paper Scissors, five rounds of Emoji Guess — because the point isn't pure competition. It's the conversation around it.
Each game is tuned so the AI plays competently but not perfectly. Tic-Tac-Toe will block you and capitalize on openings, but it won't force a draw every time. Rock Paper Scissors only starts pattern-reading from round three, so early rounds feel fair. 20 Questions runs through a language model that commits to an answer at the start and sticks with it. The design target is "fun" over "undefeated".
What actually makes AI games feel different is the chat panel running beside the board. The same companion you chose for conversation is still there — teasing you mid-move, dropping a hint when you're stuck, or bringing up a running joke from last week. Everything said during a game writes back to your main chat history, so closing the game just continues the conversation. It's the opposite of single-player: you're never really playing alone.
Tic-Tac-Toe. The AI is allowed to win, but it isn't allowed to be perfect every round. If you open in the center, it will usually open in a corner; if you play a corner, it plays center. Look for forks — positions where you threaten two wins at once — and it won't always block correctly. Best played in bursts of five or ten rounds.
Rock Paper Scissors. Pattern reading kicks in on round three. If you've been repeating yourself, the AI will notice. The trick, ironically, is not to "play random" deliberately — humans are bad at random. Mix in a short repeat on purpose (two rocks in a row) and the pattern reader will lean in, which is exactly when you switch.
20 Questions. AI-thinks mode runs a committed secret, so you can and should use binary splits ("Is it man-made?" → "Is it bigger than a microwave?"). User-thinks mode rewards specific opening hints — the AI will narrow in fast if you give it a category up front.
Emoji Guess. Each puzzle has 3–5 answer aliases and fuzzy matching, so minor typos pass. If you're stuck, wait it out — the second hint is often enough on its own. Genre hints usually come before specific cast/title hints.
Would You Rather. There's no right answer; the fun is the AI's reaction to your choice. Pick quickly and keep the rounds rolling — the replies sharpen up once the conversation builds some history.
The demo at the top of this page is real — it's the same SDK used inside the full chat experience. The only difference is the chat panel running beside the board. In a full chat, that panel is connected to your companion's memory, voice, and personality; in the demo, it's a generic "Alex" character with canned reactions. Everything else — the board, the AI strategy, the game flow — is identical. If you find yourself enjoying the demo for longer than a few minutes, that's the signal to try the full in-chat version.
