Try before you sign up
Some games are open to everyone with no account at all. Open one, play a round, and decide afterwards whether you want to keep a record of your results. Nothing is asked of you before you have seen what the game is like.

Starting out
Made to be easy to read
Text is set large, and bright elements sit on a dark background so edges stay clear during a long session. Nothing important is carried by colour alone, so the screen still reads correctly if colours are hard to tell apart.
One action to learn
Almost everything is a single tap or click. There are no swipes to remember, no press-and-hold gestures, and no menus buried inside menus. If a screen looks unfamiliar, the back control returns you to where you were.
A round a day is enough
There is no penalty for playing slowly or stopping early, and no timer running against you outside a game. Starting with one short round a day is a perfectly good way to use Quiga.
Questions we are asked most
Do I have to install anything?
No. Everything runs in the browser you already use. There is no app to find in a store, nothing to download, and nothing that asks to be updated later. Closing the page is all it takes to stop.
Do I need to sign up before I can try a game?
No. Open a game and it begins. An account is only for keeping a record: without one your results stay in that browser, and with one they stay on your account so they are still there on another device. You can play first and decide afterwards, and nothing asks for a payment method at any point.
Where do the advertisements sit? Do they cover the game?
They sit in one area below the game screen and are kept apart from the play area, so a finger that lands slightly off target does not hit one. Nothing plays before a round and nothing interrupts a round. The advertising is what lets every game stay free.
The letters look small. Can I make them bigger?
Yes. The pages follow the text size your browser or phone is set to, so raising it in your device settings makes the writing here larger as well, and the layout reflows instead of cutting words off. Buttons are sized to be comfortable to press, and if a game moves faster than you would like you can leave it at any point and come back later — nothing is timed against you.
Does it cost anything?
No. Every game here is free, and no payment method is asked for at any point — not to start, not to continue, and not to keep a record. The advertising below the game screen is what pays for the service, so there is nothing for you to arrange and nothing that can be charged to you by mistake.
