Hello, I am going to provide you with some data so you can decide whether its worth it for you to participate in the event.
I obtained 482 balls by spending 1695g for 340 rolls (including the free one). This means I got 1.41 balls per dice on average.

What did I receive in return?

I decided to take the energy rewards for 480 balls, which gave me:

125 Q5 Adrenalines
450 EBs

For calculation purposes, this is equivalent to:

4,200 EBs (if you have a 3,000 energy max and we convert the adrenalines to EB)
140 Q5 Adrenalines (if we convert EBs into Adrenalines)

Total Rewards (Including Dice Rewards):

I received 36,000 Q5 food, valued at 72g (2g per 1,000).
I got 7,300 Q5 weapons, worth 160g (22g per 1,000).
I won 7,200 Q5 tanks, valued at 158g (22g per 1,000).
Additionally, I received 8,400 Q5 airs, worth 235g (28g per 1,000).
I got 10 Q5 houses, which equals 10g (1g per house).
I received 1,200 mortars, which are equivalent to 1,500 Q5 Airs, valued at 42g (28g per 1,000).
I got 4 Q2 boosters, valued at 12g (estimated at 3g each).
I also won 20 rockets. To make 20 rockets, you would need 4 × (125 ICBM + 125 ABM, which cost 410 Q5 airs each), making the total value 45.92g (11.48g per rocket).

Energy Value

My total energy rewards were:

530 EBs
125 Q5 Adrenalines
18 Q4 Adrenalines

To fairly compare, I converted all energy into EB equivalents or Q5 Adrenaline equivalents.

This total energy is equivalent to 4,712 EBs or 157 Q5 Adrenalines.

Gold Value of Energy

If purchased from the store page, 4,712 EBs would cost 6361g (at 270g per 200 EBs). If purchased via energy packs, 157 Q5 Adrenalines would cost 9600g - 12000g (based on 4 energy packs at 12,000g or 9,600g depending on whether the pack is on discount and i consider the rate of 1 eu = 200gold).

After considering the fact that energy packs also include Q5 Boosters (not just Adrenalines) and that EBs from the store have a cooldown purchase limit, together with ChatGPT we determined that a fair price per EB equivalent is 1.5g. 

So, 4712 EBs × 1.5g = 7068g.

Final Investment vs. Returns

Total Investment: 1695g
Total Return (Fair Value): 7802.92g
Profit in Gold: 6107.92g
Profit Percentage: 359.25%

Some important notes:

1. Data from my past runs on magic balls show that you get around 1.5 balls per dice roll. This is shown by some data that was provided to me by other players as well today. So your run may be a bit cheaper, therefor with 100-200g higher profit if you do the same rewards as me. 

2. The cost and value of other rewards (without counting dice rewards):
50 rockets - 114.8G value - 425.5g dice costs - 310.7g loss, excluding dice rewards.
2000 falcons - power equivallent of 4000 q5 airs  so vallue is  112g - 355g dice costs - 243g loss, excl. dice rewards.
q4 boosters and wiper I dont feel like investing time to calculate value right now. Take them on your own decision.
