Base on my observation all Slotica Casino Free Coins bonus links will expire between 3-4 days.
If you have not played the game for a long time you can use the Slotica Casino Free Coins Bonus collector here:
It's a tool you can use to catch-up all posted links from the previous days.. With that you can pile up some free coins and start playing again.
Other Tips on Collecting from Friends post:
- All Post shares expire after 3 days. This means that 5 others have either gathered the gift, or the gift has expired.
Some Tips on Getting more Slotica Casino Free Coins
- The Daily Stamping ends after you’ve gathered the stamp from Day 28. After collecting the 500,000 bonus plus spins on day 28, it goes back to day 1.
When does the bonus coin per game level reset?
- Bonus coins per game level reset every 24 hours.
That's all Start Playing and Enjoy your Day.
