# Game System
**Interact with AI SBT CAT:**
***Start Typing***: Click “Start Typing” to initiate a conversation with your SBT pet cat. Each conversation requires consuming at least 1 Mood (Charging can restore Mood). You can earn **1–10 points** per conversation, depending on the quality of your questions. Each player can chat a maximum of **20 times** a day, so your daily score depends on the question quality. **more points means more XP= more airdrop potential**
***2.Kitty Cuddles:*** In the courtyard, remember to check-in daily to earn corresponding crystal energy flower rewards. Continuous check-ins for 7 days can give u chance to draw a lottery to get random crystal energy flowers, key or Energy Stone**(1 energy stone can restore 5 Mood)**. **P.S.: Energy stones are valuable items**.
***3.Mood***: It is a floating-point number that fluctuates based on player behavior. It affects interaction outcomes and determines whether a player can take certain actions. Many operations require Mood to proceed.
4\. ***Crystal Energy Flower***: A new type of energy generator developed by the Cat Scientist. It resembles a sunflower and can draw solar energy continuously day and night. **Every 8 hours**, it converts sunlight into an efficient energy crystal called a “Crystal nucleus.”
***Crystal nucleus***: A type of energy crystal produced by Crystal Energy Flowers. It has a multifaceted spherical appearance similar to a diamond. Its future uses remain uncertain, but it is the primary material for our mechanical pet cat’s batteries. Remember to collect it on time as it’s crucial for synthesizing batteries.
5\. ***Workshop***: Click “Workshop” to enter the workshop and see what you can do inside!
6\. ***Synthesis***: These are the Crystal nucleus we’ve collected. Let’s use them to create batteries on the synthesis platform below!
Every **20 Crystal nucleus** can be synthesized for a level 1 battery
Every **30 Crystal nucleus** can be synthesized for a level 2 battery.
7\. ***Charging***: Use batteries and energy stones to recharge your SBT cat (restore Mood).
**Battery I**: Transformed by reconstructing a certain number of Crystal nucleus, these batteries are used for daily supply to your mechanical pet cat. The energy conversion rate is low, **restoring 2 Mood per time.** Similar to a robot’s rice, you can **use up to 2 per day.**
**Battery II**: Transformed by reconstructing a certain number of Crystal nucleus, these efficient batteries are used for daily supply to your mechanical pet cat. The energy conversion rate is moderate, **restoring 3 Mood per time.** Similar to a robot’s fast food, you can **use up to 1 per day.**
**Energy Stone**: A type of energy crystal generated by some discarded battle mechs. It can be directly absorbed by any mechanical unit, has a super high energy conversion rate, and is similar to a robot’s roasted duck. There are no usage restrictions; it **restores 5 Mood at once** and gains a lot of mood, you can **use up to 1 per day.**
8\. ***Mood***: After recharging, you can see your Mood have increased. After restoring Mood, you have two ways to consume them:
1\. Click the Phantom in the bottom right corner and use it for treasure hunt tasks to consuming Mood
2\. Chat with your SBT pet cat; each consumption of 1 Mood allows you to talk to your cat 2 times.
**Why consume Mood?**
Consuming Mood can earn you “cat poops.” Collecting cat poop can be exchanged for Mystery boxes and choose either:

1\. Consumes 1 Mood and gives you a chance to get a key to open a Mystery box.
2\. Consumes 1 Mood and gives you a chance to get an energy stone.
After proceeding the treasure hunt task, your pet cat SBT will go treasure hunting. After waiting for 2 hours, you can click to see if you’ve received the reward you wanted.
Treasure Hunt fail can get a fish compensation (Eat fish to increase your **XP（Token)**
10. Click on the fingerprint icon to enter the cat’s room.
