Clapalong just announced an upcoming EXTRA LEVY event:
http://forum.clapalong.com/showthread.php?3961-Tyrant-of-Extra-LevyNote that it is not like the last event! THIS ONE SUCKS!This event only counts your
extra levies, not the levies you get naturally.
To reach 55 levies over four days you would have to levy 13 + 14 + 14 + 14 = 55.
13 levies is 14+13+12+11+10+9+8+7+6+5+4+3+2 = 104g
14 levies is 104 + 15 = 119g
So you are talking 461g - 100g (reward) = 361g for 55 levies... 7g per levy isn't exactly a steal of a deal... (normally I only pay for levies at 2g and 3g each day). And it just gets worse for the higher rewards.
If you are a super rich man (thousands of gold to burn) and are level 100+ with maxed mint and cottage you MIGHT be able to justify doing this... but for 99.99% of the players this is DEFINITELY not worth it.
