- Game type
- Board game – tic-tac-toe
- Goal
- Line up three X or O marks before your opponent.
- Controls we used
- Click or tap a square. Menu buttons: Easy, Hard, Two Player and Play Online.
- On a phone (390px test)
- Yes – the board and all four buttons fitted the 390px portrait screen without scrolling.
- Load time
- Title screen in about 1 second.
- Difficulty
- Easy mode is beatable in a few moves – we won our first game with a diagonal. Hard mode and online play are there for more challenge (we did not test online play).
- In-game ads
- Yes – the GameMonetize video-ad system (Google IMA) loads with the game.
- How a session plays
- The board is live straight away: clicking squares started a round against the computer, and a green line marked our winning diagonal after five moves. Two Player mode lets two people share one screen.
Our verdict: Simple, bright tic-tac-toe with difficulty levels and a pass-and-play mode – handy for a 30-second game.
How we test: we open the game in a desktop browser and in a 390px-wide phone view, time how long it takes to load, play through the opening level or round and note exactly what we saw. We only write down things we observed. More about our testing.
