How to Play Hanafuda
Welcome to Hanafuda!
In this article, weโll explain the key terms used in Hanafuda and guide you through the gameplay.
About Hanafuda
Hanafuda is an application designed to connect you with the world envisioned by the Hana Network. By depositing major cryptocurrencies like ETH and USDC, you can earn points and Hanafuda cards, which you can then use to play. You can also create your own team (Garden) and invite others to join, increasing your chances to earn even more points and Hanafuda cards.
Letโs dive in and get started with Hanafuda!
Creating and setting up your account
1. Creating a Hana account
Sign up using Google, then enter an invitation code (a six-character alphanumeric code).
Existing users can generate invitation codes. Get an invitation code from someone whoโs already part of the community, possibly through social media.
- There is no limit to the number of people you can invite with a single code.
- Existing users can only generate an invitation code if they have made at least one deposit.
2. Setting up your profile
After logging in, click on the user icon displayed in the header to make the following changes:
- Change icon: You can upload any image (PNG, JPEG, JPG, up to 2MB).
- Change username: You can use only alphanumeric characters and underscores. If the username is already in use, youโll need to choose another one.
These settings are visible to others when viewing leaderboards or team members, so make sure to choose an icon and username you like!
Youโre now ready to start playing Hanafuda. The next step is to make a deposit. Letโs go over how to do that.
Making a deposit
To play Hanafuda, you need to deposit supported cryptocurrencies. Letโs walk through the process.
First, letโs review the supported blockchains and tokens for Hanafuda.

- ARB: 0x912CE59144191C1204E64559FE8253a0e49E6548
Now, letโs proceed with making a deposit.
1. Connecting your wallet
First, click on โConnect Walletโ to link your wallet to Hanafuda.
Make sure your wallet address appears above the button โ it confirms the connection.
2. Linking your wallet address to your hana account (if not already linked)
Youโll need to link your wallet address to your Hana Account. This is a one-time process, and once itโs done, you wonโt need to repeat it.
Click โSet up your Hana account,โ sign the request in your wallet, and your Hana Account will be linked. Afterward, your linked address will appear below the Hana Account.
Always use this linked address for deposits. Trying to deposit from a different address will trigger a warning.
Note: If you need to change the linked address, you can disconnect it. However, deposits made directly to the smart contract without using the UI wonโt be supported by Hanafuda.
3. Making a deposit
Choose the blockchain and token, specify the amount you wish to deposit, and click the โDepositโ button.
The deposit button wonโt appear until youโve completed the previous steps.
In Hanafuda, your deposit score is based on the number of transactions rather than the amount of each deposit. The minimum deposit amount varies by token.
For example:
- ETH: 1 wei (=10^-18)
- USDC: 10^-6
- WBTC: 10^-8
Deposits have no fee.
For ERC20 tokens, you must approve the transaction first. If the โApproveโ button appears, complete that process before depositing. ETH deposits donโt require approval.
Please note that direct deposits to the smart contract, outside of the UI, may take longer to reflect on your deposit score.
Withdrawals will be available starting early Q1 2025.
After depositing, invite your friends to Hanafuda to grow your Garden.
Garden
A Garden is essentially your team, and any users you invite will become part of your Garden.
These invited users can also create their own Gardens. However, only the users who joined using your invitation code will belong to your Garden.
Creating a Garden means that the deposit counts from all its members, including your own, are combined and used to calculate your Garden Rewards. The more users you invite and add to your Garden, the easier it becomes to earn Garden Rewards. For more details, please refer to the Garden Rewards section.
Additionally, with the Grow feature, a portion of the points earned by users you invited will be added to your total as well. Check out the Grow section for more information.
Keep in mind that inviting users alone wonโt earn you rewards.
How to issue an invitation code
Click the โInviteโ button on the dashboard to copy your invitation code to the clipboard.
Note: The Invite button will only be active if you have made at least one deposit.
Next, letโs dive into Grow and Garden Rewards, the main features of playing Hanafuda.
Grow
Grow is like a roulette or gacha game. You can earn between 100 to 1,000 points randomly each time you play.
Relationship between deposit count and grow attempts
The maximum number of Grow attempts depends on your deposit count. Hereโs how it works:
Boosting Grow
When you make 5,001 or more Deposits, a Boost will be applied to the Grow Value you acquire. The relationship between the number of Deposits and the Boost multiplier is as follows:
For Example:
- Deposit Counts: 10,000
- Acquired Points: 500
- You get 2,500(= 500 * 5) Points
Every Hour, the number of deposits is checked, and the maximum number of Grow attempts is updated accordingly.
For example, if you have made 5 deposits, you would receive 20 Grow attempts. If you use all 20 attempts, reducing your remaining Grow attempts to 0, your count will reset to 20 the next Grow replenishment timing, as long as your total deposits remain at 5. If you have 10 Grow attempts left by the next Grow replenishment timing, they will simply be replenished to 20; they wonโt add up to make 30 Grow attempts.
1-Click Grow
1-Click Grow, which allows the remaining number of Grow executions to be consumed at once, is available; the Point result from Grow is increased by the number of executions consumed.
For Example:
- Acquired Points: 500
- Number of Grow consumed: 20
- You get 10,000 (= 500 * 20) Points
Grow garden member bonus
When a Garden member youโve invited performs a Grow, a portion of the points they earn will also be awarded to you as their inviter.
- If User A, whom you invited, earns points, 16% of those points will be given to you.
- If User A invites User B, and User B earns points, 8% of those points will be awarded to you.
For example:
Alice invites Bob, and Bob invites Jack. In this scenario:
- If Alice earns 100 points โ Alice: +100 points, Bob: +0 points, Jack: +0 points
- If Bob earns 100 points โ Alice: +16 points, Bob: +100 points, Jack: +0 points
- If Jack earns 100 points โ Alice: +8 points, Bob: +16 points, Jack: +100 points
This is how points are distributed accordingly.
Garden Rewards
Garden Rewards are the key to earning Hanafuda cards. You can use one Garden Reward to obtain one Hanafuda card.
Hanafuda is a traditional Japanese card game featuring vividly illustrated cards depicting animals, plants, and other elements. Players collect these cards to form specific hands and compete for points. For more details on the Hanafuda cards and hands, please refer to the Hanafuda Collections section.
Garden Rewards are awarded based on the total number of deposits made by your entire Garden.
While Grow is based on your individual deposit count, Garden Rewards are calculated based on the combined deposit counts of both you and the users you have invited to your Garden.
Relationship between deposit count and garden rewards
1.Regular Rewards
You earn 1 Garden Reward for every 5 deposits made.
2.Milestone Rewards
When you reach specific deposit milestones, you earn bonus Garden Rewards as shown in the table below.
Milestone Rewards
For example:
If your Gardenโs total deposit count reaches 50:
- Regular Rewards: 50 / 5 = +10
- Milestone Rewards: +3
- Total: +13 Garden Rewards
Note on garden rewards timing
The calculation and update of Garden Rewards based on your Gardenโs deposit count happen every 1 minutes. So, there might be situations where your personal deposit count increases, but the Gardenโs deposit count hasnโt updated yet.
Letโs take a closer look at the Hanafuda cards and the hands you can create using your Garden Rewards.
Hanafuda collections
Hanafuda cards are divided into four types for each of the 12 months, with each type appearing across four different seasons, resulting in a total of 192 unique cards.
12 months * 4 types * 4 seasons = 192 cards
Note: The seasonal variation is a unique feature of Hanafuda within the Hana Network.

Share bonus
Creating a Garden gives you an advantage in the game, and the key is to share the excitement of Hanafuda and invite new members. To encourage sharing, we offer bonus points as an incentive.
Whenever the Share button appears during the following moments, click it to post on X (formerly Twitter) and share the fun of Hanafuda to earn 50 bonus points:
a. When you earn points through a Grow action
b. When you create a hand by revealing Hanafuda cards
You can earn the Share bonus once every 24 hours. After claiming the bonus points, thereโs a 24-hour cooldown period during which you wonโt be able to earn additional bonus points by posting on X (formerly Twitter).
Each of these actions (a and b) has its own separate cooldown period, so you can still earn a Share bonus for completing a hand even if youโve already claimed a bonus for a Grow.
Curious about how your points compare to others? Check out the leaderboard!
Leaderboard
The leaderboard displays the top 100 users ranked by their points. In the case of a tie, the user who made the most recent deposit is ranked higher. Users who joined through a special initial invitation code and have no inviter are labeled as โHANA-OG.โ If you donโt rank in the top 100, your status will be shown as โOut of Rankโ (โ-โ).
