Best Resource Strategy in Unsolved: Hidden Mystery Games
Unsolved: Hidden Mystery Games uses several resources to support its investigations and adventures.
Energy, Gems, Hints, and Keys have different purposes. Managing them carefully can help you avoid running out of resources when you want to continue playing.

Save Gems for Resources You Actually Need
Gems can be obtained through adventure rewards and daily gifts. They can also be purchased through in-app purchases.
One important use for Gems is purchasing additional Energy or Hints.
Before spending Gems, check whether the resource can recover over time or be obtained through another free option.
Let Energy Recharge Naturally
Energy restores automatically over time.
According to the official support center, one Energy point regenerates every 4.5 minutes.
You can also obtain Energy through:
- Watching advertisements.
- Claiming Daily Gifts.
- Following the game’s Facebook page for a one-time reward.
- Purchasing Energy with Gems.
If you are not in a hurry, waiting for regeneration can help preserve your Gems.
Use Hints When You Need Them
Hints also restore over time.
The official support information lists advertisements and Gems as additional ways to obtain Hints.
Avoid spending Gems immediately whenever you get stuck. First consider whether waiting for natural regeneration is a better option.
Understand How Keys Work
Keys are used to unlock new adventures.
The official support page states that making any purchase in the game grants unlimited Keys permanently on that device. It also lists Key Recharge Events as another way to replenish Keys.
This is an important distinction: the documented unlimited-Key benefit is linked to a purchase, not simply to daily gameplay.
Final Thoughts
The best resource strategy in Unsolved is to use free regeneration and daily rewards before spending Gems. Save premium resources for situations where you need to continue an investigation or solve a difficult puzzle.
