A Fork of a Blockchain Game Spaceship from Four Years Ago: Cryptoplants
• By vski5 • 4 minutes readGame Introduction
Cryptoplants is an NFT game inspired by Plants vs. Zombies, where players spend money to mint plants and houses, defeat zombies, and earn $CP.
The game is a pixel-perfect copy of CryptoMines (with the spaceship token Eternal), attempting to replicate its get-rich-quick myth.
Gameplay
Players need to spend $CP to mint houses and plants, both costing 100 $CP per draw. The higher the rarity of the cards drawn, the higher the level of zombies they can defeat.
Currently, minting is not available on the testnet, and the mainnet is not launched yet: 
Houses
Each player can mint up to five houses. The number of plants a house can hold and their drop probabilities are listed below:
| Rarity | Drop Rate | Plant Capacity |
|---|---|---|
| 5 Star | 1% | 5 |
| 4 Star | 5% | 4 |
| 3 Star | 15% | 3 |
| 2 Star | 35% | 2 |
| 1 Star | 44% | 1 |
Plants
There is no limit to how many plants can be minted, and plants can be destroyed. If destroyed, 20% of the minting cost in $CP is refunded.
Each plant can only kill one zombie every 24 hours. The zombie-kill quota for all players resets daily at 00:00 UTC.
Houses are not subject to this restriction, so multiple plants can take turns fighting zombies inside a house. In my opinion, it’s important for a single address to have many high-level houses.
| Rarity | Drop Rate | Min MP | Max MP |
|---|---|---|---|
| 5 Star | 1% | 200.00 | 255.00 |
| 4 Star | 5% | 150.00 | 200.00 |
| 3 Star | 15% | 100.00 | 150.00 |
| 2 Star | 35% | 50.00 | 100.00 |
| 1 Star | 44% | 15.00 | 50.00 |
Guard Squad = House + Plants
A Guard Squad consists of houses and plants. Adding a house or plant costs $0.5 worth of $CP. If added after charging, it costs $0.5 + $3 worth of $CP.
A Guard Squad must be fully charged to defend against zombie invasions. There are three charging packages available:
| Charge Count | Cost per Plant (in $CP based on oracle price) |
|---|---|
| 7 Charges | $7 USD |
| 15 Charges | $14 USD |
| 30 Charges | $27 USD |
You can freely combine or remove houses and plants in a Guard Squad. However, if the squad has fought zombies on the same day, it cannot be disbanded.
This means having many high-level plants may not be very beneficial. Rearranging Guard Squads is expensive, and rotating different plants within the same house might be a tactic worth testing.
Killing Zombies = Earning Money
Guard Squads choose which zombie to fight. You can have five squads all fight the same zombie type.
Victory Rate = Base Rate + (Current Power - Required Power) Ă— (97% - Base Rate) Ă· (6375 - Required Power)
- If your power equals the zombie level’s minimum required power, your win rate equals the base rate.
- If your power is much higher than required, your win rate approaches the maximum of 97%.
| Zombie Level | Base Win Rate | Minimum Required Power |
|---|---|---|
| 1 | 93% | 100 |
| 2 | 91% | 200 |
| 3 | 89% | 300 |
| 4 | 87% | 400 |
| 5 | 85% | 500 |
| 6 | 83% | 600 |
| 7 | 81% | 700 |
| 8 | 79% | 800 |
| 9 | 77% | 900 |
| 10 | 75% | 1000 |
| 11 | 71% | 1100 |
| 12 | 69% | 1200 |
| 13 | 67% | 1300 |
| 14 | 65% | 1400 |
| 15 | 63% | 1500 |
| 16 | 61% | 1600 |
| 17 | 59% | 1700 |
| 18 | 57% | 1800 |
| 19 | 55% | 1900 |
| 20 | 53% | 2000 |
| 21–25 | 52% | 2100–2500 |
| 26–30 | 50% | 2600–3000 |
Earnings & Strategy Analysis
The game’s earnings are “stable,” and many elements benefiting the developers are USD-pegged.
However, both the game’s values and economic model are poorly designed. The pixel-perfect copy is not good: the original game’s token (Eternal) dropped from over $700 to zero in just two weeks. According to experienced players, even early participants took about a month to break even.
Another major downside is that this game doesn’t even have its own art—no AI pixel art either.
Let’s assume great luck: with 500 $CP, you draw five level-5 houses, and each house contains five 5-star plants. One house’s power = 225 × 5 = 1125. Five such houses form a squad with total power = 1125 × 5 = 5625, targeting Level 30 zombies.
Win Rate = 50% + (5625 - 3000) Ă— (97% - 50%) Ă· (6375 - 3000) = 86.55%
If using only three houses at full capacity, then: Win Rate = 50% + (3375 - 3000) Ă— (97% - 50%) Ă· (6375 - 3000) = 55.22%
This shows how poorly the game’s numbers are designed.
Cost incurred so far:
- 500 $CP (houses)
- 12,500 $CP (25 plants)
- $0.5 Ă— 30 = $15 (adding 25 plants + 5 houses)
- $1 (approximate cost of one charge)
Rewards are not publicly disclosed. 
Dynamic Stablecoin Reward Mechanism
Rewards from killing zombies depend on the level of your Guard Squad and the zombie defeated. An oracle mechanism is used to keep reward value stable in USD and prevent rapid depletion of the reward pool.
Early Withdrawal Tax
A 30% fee is charged for claiming $CP rewards early. This decreases by 2% per day after your first zombie kill. For example, on the second day the fee is 28%, and so on.
By Day 15, the fee drops to 0%, allowing tax-free withdrawals.
NFT Trading
Whether buying or selling NFTs on the marketplace, a 15% transaction fee is charged. This fee is fully returned to the Rewards Pool.
