Terms of Use
Welcome to 100 yen games. Here are a few things to know about playing, saving progress and making support payments, so your family knows what to expect.
The games are free
You can play without an account or subscription.
If you’re an adult and would like to support the games, you can make an optional payment through Stripe. Each payment is a one-time choice. You won’t be charged again automatically.
Supporting the games doesn’t give anyone extra plays, paid prizes or an advantage in the games.
Choose play limits that suit your family
Daily play limits are there to help your family manage play time. You can change them through the PARENTS settings.
Each player’s limit is shared across all games on this site.
A simple question helps prevent accidental changes to the parent settings. It isn’t an identity check or a password-protected lock.
A note about saved progress
Progress and collections are saved in your browser. They aren’t stored in the cloud or automatically transferred to another device.
Clearing your browser’s stored data or switching devices may mean your earlier progress is no longer available.
If something goes wrong with saving, we pause play and let you know so you can address the problem.
Please help keep things enjoyable
Please don’t disrupt the website or interfere with anyone else’s use of it.
You’re welcome to enjoy the games, but playing doesn’t transfer ownership of the artwork or software to you.
Support payments and refunds
Support is optional, for adults only, and paid one payment at a time.
Once a payment is complete, we generally can’t accept cancellations or refunds for a change of mind or other personal reasons. Please check the amount before paying.
We will address payment processing errors on our side, such as duplicate charges, and refunds required by applicable law. If you need help with a payment, please use our contact form.
You’ll find the amounts and payment conditions in Service / Support Info. These terms don’t limit any rights you have under applicable law.
Updates and availability
The games may change, and they may become unavailable.
Support helps with the development and operation of our free games. It doesn’t come with a promise of new games, continued availability or any particular feature being completed.
Questions are welcome
100 yen games is operated by Yamaguzzi LLC.
