need help from some slots-whore-pro's

[teleman]

hello,
i got catched by a countryspecific bonus at a microgaming-viper-casino (jackpotcity)
WR: 20x(d+b)=6000wr -SLOTS-ONLY!!!- required to playthrough!!!!
i've gambled my deposit up like a normal-mgv-ev-bonus to 1000 (then i saw that the terms are different to the normal standard terms. so i'm looking for a way to play

my ideas till now:

1. playing a 25line-videoslot (low(est) jackpot, many extra- features) with 1cent per line to meet the wr..and hope didn't to loose very much or get broke/busted (f.e: Loaded-slot)

2. playing a single-line-reel-slot (low(est) jackpot) and hope. (f.e: double-magic-slot)

3. playing anything aggressively to win anything bigger, or big enough, to grind this with a any other slot out. (don't know what could be the best for this)

(it is okay for me to lose my initial deposit of 50Eur, for any aggressive strategy )

i would be very happy for any advises, experiences, new ideas or just evaluations.

thanks
