Lowers Sulphur/Sulfur demand
Pyrotechnics ( Military )
Expansion requirements:
Wood and Marble
Use requirements:


The constant exercises with the fireworks don't only light up the skies, but sometimes also the surrounding buildings. Our researchers, though, can only optimize the demand for sulphur, when they test new mixtures again and again.

  • Every level of the Firework Test Area lowers demand for Sulphur/Sulfur by 1% per expansion (only in the town it is built).

Explanation of Reduction Buildings

All reduction buildings add their deduction percentage to that given by Pulley, Geometry and Spirit Level. This means the actual discount is an additional 1% per level of the reduction building, plus the reduction from the level of research you have completed. For example, a Level 1 reduction building combined with Pulley has a net of 3% reduction, with Geometry there is a net of 7%, and with Spirit Level there is a net of 15%. With the maximum level of reduction buildings (Level 32, 32% reduction) and Spirit Level (14%), the maximum reduction for that resource is 46%. This means you use only 54% of the original cost.

Expansion Details[]

The time (in seconds) it takes to upgrade to the next level is determined by the following formula:

The accumulative time (in seconds) it takes to upgrade up to the next level is determined by the following formula:
