One of the most Frequently Asked Questions is how to obtain without actually purchasing them.
A regular way is to participate in the weekly Challenges (see for example Dino Week) that often (but not always!) have a Crystal reward. This page in particular aims to start up a description of a particular method of 'Getting Free Crystals' for Android Player.
DISCLAIMER: I have not gone into length for this topic already. So please contribute, correct and discuss.
Cross Selling from Tiny Village to other games
On Android devices a cross selling method is available (at some device?) that allows (some?) players to obtain by for example installing other (free) games or participate in on-line inquiries (in my view a risk for spam).
Some experience has been obtained (Fanoftinyvillage). The description below is based on this (limited) experience.
Trivia on experience gained
- So far I have been able to add some 50 for just installing some games (it takes some time but not much more).
- I have been hesitant to participate in on line quizzes and inquiries as these ask for permission to send you mail.
