What is a rok speedup calculator?

A rok speedup calculator is an essential tool for players of the popular mobile strategy game, Rise of Kingdoms. Its primary purpose is to help you manage your most valuable resource: time. The calculator takes a specific timer you want to finish—like a building upgrade, technology research, or troop training—and your current inventory of speedup items, then computes the most efficient combination of items to use. This prevents wasting precious speedups and ensures you use the right items for the job. Instead of guessing or manually adding up minutes and hours, this tool provides an exact plan, making it a cornerstone for any serious player’s resource management strategy.

The rok speedup calculator Formula and Explanation

The logic behind an effective rok speedup calculator isn’t a single mathematical formula but a “greedy algorithm.” The principle is simple: always use the largest available speedup that doesn’t exceed the remaining time. This ensures that you don’t waste a 3-hour speedup on a 2-hour timer, for example. The calculator converts your target time into a single unit (usually minutes) and then works its way down your inventory, from the highest value speedups (like 7-day items) to the lowest (1-minute items), subtracting from the total time with each step.

Algorithm Variables
Variable Meaning Unit Typical Range
T_remaining The total time left on the project timer. Minutes 0 – 500,000+
S_value The time value of a specific speedup item. Minutes 1, 5, 60, 480, etc.
S_inventory The quantity of a specific speedup item you own. Count (unitless) 0 – 10,000+
S_to_use The calculated number of a specific item to use for maximum efficiency. Count (unitless) Calculated by the algorithm

Practical Examples

Example 1: Finishing a Long Research

Let’s say you have a research project with 12 days, 5 hours, and 30 minutes remaining. Your goal is to finish it instantly for an event.

  • Inputs: 12d, 5h, 30m. You have plenty of all speedup types.
  • Calculation: The calculator converts this to 17,610 minutes. It will first use one 7-day speedup, then one 3-day speedup. The remaining time is 2 days, 5 hours, 30 minutes. It then uses two 24-hour speedups, one 3-hour speedup, and finally two 15-minute speedups.
  • Result: The calculator would recommend using: 1x 7d, 1x 3d, 2x 24h, 1x 3h, 2x 15m.

Example 2: A Quick Troop Training with Limited Speedups

You need to finish a troop training batch that has 4 hours and 23 minutes left. You have no 3-hour or 60-minute general speedups.

  • Inputs: 4h, 23m. Your inventory is low on medium-sized speedups.
  • Calculation: The calculator sees you have no large speedups to use. It will move down to the next available, which might be 30-minute items. It would calculate using eight 30-minute speedups, two 10-minute speedups, and three 1-minute speedups.
  • Result: Use: 8x 30m, 2x 10m, 3x 1m. It will also show you that you used a less optimal combination due to inventory limitations. For better training plans, see our RoK troop training calculator.

How to Use This rok speedup calculator

  1. Enter Target Time: In the “Target Timer” section, input the remaining days, hours, and minutes on your building, research, or training project.
  2. Select Speedup Type: Choose the specific type of speedup you plan to use (General, Building, etc.). This ensures the calculator prioritizes specialized speedups if you were to input them separately. For this calculator, we assume you’re using General speedups or have a mix that includes them.
  3. Input Your Inventory: Fill out the “Your Speedup Stash” section with the quantity you own of each speedup denomination. Be as accurate as possible.
  4. Calculate: Click the “Calculate” button.
  5. Interpret the Results: The results box will appear, showing you the exact number of each speedup to use for optimal efficiency. It will also tell you if you have a shortfall and how much time is remaining. A chart will visualize the contribution of each speedup type.

Key Factors That Affect Speedup Usage

  • Alliance Helps: This is the most crucial factor. Always get maximum helps from your alliance *before* you even think about using speedups. Each help reduces the remaining timer, significantly lowering the number of speedups needed.
  • Runes: Activating a rune for building, research, or training speed before starting a project reduces the initial total time. A 10% research rune can save you hundreds of hours on long-term projects.
  • Kingdom Buffs: The King can activate kingdom-wide buffs that increase building, research, or training speed. Always check if one is active before starting a large project.
  • VIP Level: Higher VIP levels grant a permanent boost to building and research speed. At VIP 10 and 15, these bonuses become very significant. This is a key part of any MGE planning guide.
  • Civilization Choice: Some civilizations offer innate buffs. For example, China has a building speed bonus, and Korea has a research speed bonus.
  • Holy Site Buffs & Titles: Capturing holy sites provides alliance-wide buffs, and titles granted by the King (like Justice or General) can also provide powerful, temporary speed boosts.

Frequently Asked Questions (FAQ)

1. Should I use specific speedups (e.g., Building) before general ones?

Yes, always. Specific speedups can only be used for one purpose, while general ones are flexible. This calculator’s logic assumes you’d use the specific ones first, so use your general speedup inventory here to cover the rest.

2. Why does the calculator tell me to use so many small speedups?

This happens if you don’t have enough larger-denomination speedups to cover the timer. The algorithm moves down to the next available size, which might be smaller items. It’s a sign your inventory is imbalanced.

3. When is the best time to use speedups?

The best time is during a “More Than Gems” event or another event that gives you rewards for using speedups. This way, you get double the value: progress on your upgrade and points/rewards from the event.

4. Can the rok speedup calculator account for alliance helps?

No, you must account for them yourself. Wait until you have received all alliance helps and the timer has been reduced, then input the *final* remaining time into the calculator.

5. Is it better to save speedups or use them immediately?

For new players, it’s often better to use them to rush your City Hall and key technologies to unlock more power faster. For advanced players, saving them for major event pushes (like for a governors event guide) is more strategic.

6. How can I get more speedups?

You can get them from completing daily objectives, participating in events, defeating barbarians and forts, alliance gifts, and purchasing them from the VIP shop.

7. Does this calculator work for healing troops?

Yes, the logic is the same. Simply choose “Healing” as the speedup type and input your healing speedup inventory alongside your general ones. A good strategy is vital for RoK resource management.

8. What if I don’t have enough speedups?

The calculator will tell you how many speedups you used and show the remaining time that you could not cover. This helps you know exactly what you need to acquire to finish the project.
