Coins disappear fast in Tower Defense Simulator, especially when back-to-back skin crates drop like Valentine and Lunar New Year events. If you are trying to unlock multiple crates without running out of currency, you need a method that is consistent and solo-friendly. This guide explains one of the best grinding strategies right now and how to maximize your coin income per hour.
Tower Defense Simulator is one of the most popular strategy games on Roblox. Players defend against waves of enemies using different towers, modifiers, and skill trees. Coins are the main currency for buying crates, skins, and upgrades, while gems are used for special unlocks. Because cosmetic crates can be expensive, efficient farming is important.

The Best Solo Grinding Method
One of the strongest solo farming strategies currently is called Final Brain Cell. The main advantage of this method is that you do not need a team. It is designed for solo players who want steady income without complicated coordination.
1. Base Earnings (No Boosts)
Without using Skill Tree bonuses or Time Scale modifiers, you can expect:
- Around 7,200 coins per hour
- Around 360 gems per hour
This is already solid for a relaxed solo grind.
2. Boosted Earnings (With Skill Tree + Time Scale)
If you activate Skill Tree upgrades and Time Scale:
- Up to 17,500 coins per hour
- Up to 840 gems per hour
That is more than double the base amount. You can also stack additional modifiers to increase rewards even further, depending on how confident you are with the setup.
Why This Strategy Works
The Final Brain Cell strategy focuses on:
- Efficient wave clearing
- Stable defense scaling
- Minimal risk of early leaks
- Fast match completion
Since it is optimized for solo runs, you do not waste time waiting for teammates or dealing with uncoordinated placements. The consistency is what makes the hourly coin rate strong.
Tips to Maximize Coin Farming
To get the best results:
- Stick to the exact tower placement order used in the strategy.
- Avoid unnecessary upgrades early on to maintain economy balance.
- Use Skill Tree bonuses focused on income and damage efficiency.
- Enable Time Scale if your build can handle the faster pacing.
- Stack reward modifiers carefully if you want higher payouts.
Running clean and fast matches repeatedly is more important than trying risky setups that might fail.
Is This the Best Way to Farm Crates?
For solo players, this is currently one of the most efficient and low-stress coin farming methods. With proper boosts, reaching over 17,000 coins per hour makes buying expensive crates much more manageable. If you are grinding for Lunar New Year skins or future limited crates, this strategy helps you rebuild your coin balance quickly. If your goal is steady income without depending on a squad, the Final Brain Cell method is one of the strongest options available right now.
