Thinking about doing it

Appropriate Target Level: For non-paying players, levels between 40-60 are generally realistic. However, reaching the high-reward tiers of 250-270 requires significant time, luck, or spending. Time per Mission: While the early stages (levels 40-70) can be cleared within a few days with 8-12 hours of focused play daily, construction costs increase exponentially in the mid-to-late game, sometimes taking over 15 days to complete. Special Mission Progress Recommendation: Special missions and events are key ways to obtain a large amount of dice, but it's easy to run out if you rush blindly. Tip: Save your dice early in the event and collect free dice. Use them strategically for high multiplier opportunities or when competing for rankings (tournaments). It's advantageous to push hard at the right moments.

If you consistently watch ads and reach level 151, it's manageable.
