What is the FoE Arc Calculator?
The FoE Arc Calculator is an essential tool for high-level Forge of Empires players. It calculates the “Lock” point—the moment an investor can place Forge Points such that no other player can overtake them, even if the second player fills the rest of the level.
By leveraging the Arc’s massive contribution bonus, guilds often organize “1.9 threads” where players donate 190% of the base reward to each other. This calculator ensures the owner has contributed enough points so that these 1.9 investors don’t lose their spots to “snipers.”
How to Calculate FoE Arc Secure Points (Example):
- Identify the total cost of the level (e.g., 2000 FP).
- Note how much the owner has put in (e.g., 800 FP). Remaining is 1200.
- Find the reward for Position 1 (e.g., 400 FP).
- At a 1.9 rate, the investor brings 760 FP.
- Formula: (1200 + 760) / 2 = 980. The owner needs to reach 980 FP total to “lock” P1 at 760 FP.
Frequently Asked Questions (FAQ):
Is the 1.9 bonus the highest possible? No, high-level Arcs (above level 80) can provide bonuses exceeding 90%, sometimes reaching 100% or more.
What is “Sniping” in FoE? Sniping is when a player invests in your GB for profit without being part of a reciprocal thread, often securing a spot for less than the 1.9 rate.
Do I need an Arc to use this? No, this calculator helps owners prepare their buildings for others, as well as helping investors check their own safety.
Why is my result negative? A negative result usually indicates the position is already secure or the inputs are mathematically impossible for the current level state.
