This is an offer that I received from Eurobet.
How hard is this bonus to clear?
5. This is a release-restricted bonus - you will not receive the bonus chips until you have met the following criteria:
Bonus funds will not be credited to your Poker balance until you have generated 10 times the amount of player points for each $1 of bonus received. For example to clear a bonus of $600 will require 6000 points.
6. Player points are accumulated by playing ring games and tournaments. Points are awarded at a rate of 0.07 points for each $0.10 of rake in a ring game. For example a rake of $3 will award all players contributing to the pot 2.1 points. For tournaments points are awarded at a rate of 5 points for each dollar of tournaments entry fee paid. For example if a player enters a $10 +1 tournament, he will receive 5 points.
7. The required number of points for bonus release must be generated within 90 days of first triggering the bonus. If this has not been achieved then any bonus funds due will be withdrawn.
