In this version, you can play four rivers: the Arakawa River, the Nile River, the Yellow River, and the Mekong River.

[How to play]
(1) Select a river.
(2) Tap or swipe to create waves to move river litter to the white basket and collect it.

*If you succeed in collecting river litter, you will get coins that can be used in the APP.
*If you fail to collect river litter, you will lose coins.
*If you successfully collect river litter in succession, a combo will be formed, and "creatures unique to that river" will appear depending on the number of combos you have performed. Also, a "Combo Bonus" will be added when a combo is successfully completed, and more coins will be obtained.
*Various "titles" can be obtained according to the maximum number of combos.
*River litter will flow forever.

[Time Warp]
Using the time warp function, you can time warp to the past. The types of "river litter" and the creatures that appear will differ depending on the time period.

[ZEN Mode]
Tap the switch in the upper left corner of the play screen to display the options screen. The switch in the options screen allows you to switch to "ZEN Mode.

[Interlocking with reality]
If you watch the video advertisement or purchase NFT art, our staff will actually collect "river litter" in a "real river".

The following two plans are available.

#Plan-A
Watch the video ad (30 seconds)
You will get 4000 in-app coins.
Our staff will collect 2 pieces of river litter in a real river.

#Plan-B
You purchase special NFT art at OpenSea (FLOAT-RiverLitter).
Our staff will collect "1 liter of river litter per 0.002eth" in a real river.
*Price per piece of NFT art varies depending on the item.
*The amount of collection may change if the price of ethereum fluctuates significantly

*For the time being, the left bank of the mouth of the Arakawa River (around 3 km upstream from Tokyo Bay) will be the river litter collection area (as more river litter washes ashore at this location).

You can check the total number of times your video ad has been viewed on the dedicated website.
(Tap the "i" icon on the lower left of the video ad icon in the app > tap "FLOAT REPORT" > go to the dedicated site).
Please note that there is a time lag of up to several weeks between the time the numbers are posted to the dedicated site.

The "cumulative number of video ad views" will be displayed on this site periodically, and a "proof photo" will be posted to prove that the corresponding "river litter" has been collected.
Please check the OpenSea website for the number of NFT art sales.

This is a social experiment, and we plan to improve it through trial and error. The proceeds will be used for practical and educational activities to solve the problem of river/ocean litter.

[Please note the following]
This APP is not an endorsement of the elimination or non-use of plastic products. Plastic products are very useful and beneficial materials for making products, and our society would not be able to survive without them. We believe that illegal dumping, improper management, and excessive use are the three main problems.
