Studio
FREE BROWSER GAMES
No install. No sign-up. Just play.
UAJ Studio makes free games that run right in your browser. There is nothing to install and no account to create. You can play Typing Battle, a real-time 1v1 typing duel, right now. Next up is Stella Orbs, a falling-orb puzzle in which you fight with a party of constellation spirits. It is getting ready for release, and no date is set yet.
Type the word on screen correctly to hit your opponent; mistype and you take damage yourself. Whoever drains the other's 1000 HP first wins. It rewards accuracy as much as speed, and matches are short.
Team up with spirits from world mythology and clear three-orb pieces falling onto a hexagonal honeycomb board to fight enemies. Build a ring, a pyramid or a line out of six orbs and every orb of that color on the board disappears for big damage.
UAJ Studio builds small games that you can open in a browser tab and play in a few spare minutes, but that still have enough depth to keep you coming back. We started with Typing Battle and are now building a second game, the puzzle battler Stella Orbs.
Typing Battle is a real-time 1v1 duel. Both players start with 1000 HP. Every time you finish a word you damage your opponent, and every time you hit a wrong key you damage yourself. The first player to bring the other to 0 HP wins.
Finishing a word deals 50 + 25 × units damage, capped at 250. In English mode a unit is one letter. (In Japanese mode a unit is one kana, with small-kana pairs such as "きゃ" counting as one.) A mistake always costs you a flat 25 HP, no matter how long the word is.
| Word | Letters | Damage dealt |
|---|---|---|
| cat | 3 | 125 |
| love | 4 | 150 |
| cloud | 5 | 175 |
| flower | 6 | 200 |
| mountain | 8 | 250 (the cap; 8 letters or more all deal 250) |
Four mistakes (100 HP) cancel out a whole 2-unit word. Accuracy matters at least as much as raw speed.
In English mode you type each word exactly as it is spelled, in lowercase, one letter per unit. The words are everyday vocabulary plus some English internet slang. You choose the language of your words (the prompt language) in the lobby, separately from the display language. English and Japanese are the main modes, and Portuguese, Spanish, French, German and Indonesian prompts are available too. For English, the keys a to z and - are used; for the languages with accents, accented letters and the same letters without accents are both accepted.
| Mode | Login | How it works |
|---|---|---|
| Casual Match | Not needed | Press the button and an opponent is found. No ranking points change hands. |
| Play with Friends | Not needed | Create a 6-character room code, share it, and the friend who enters the same code is your opponent. |
| Ranked Match | Required (sign in) | Ranking points go up or down with each result. Every 1000 points moves you up a tier, across 16 tiers in all. |
When you play signed in, your match history page shows average typing speed, miss rate and which keys give you the most trouble. The detailed rules are summarized at the bottom of the Typing Battle page.
STELLA ORBS
Stella Orbs combines a falling-block puzzle with a party battle. You team up with spirits of the constellations, drawn from world mythology. Pieces of three orbs in five elements (fire, water, grass, light and dark) fall onto a honeycomb board of hexagonal cells, and connecting six or more orbs of one color makes your party hit the enemy.
The game is still getting ready for release, so characters, rules and screens may change. The characters, how to play and the full list of numbers are on the game guide pages.
