For 100% up to 500 per week, I would have a look.
I suspect the promotion is aimed at slots players, and although other games can be played with zero weighting, this is best avoided as I suspect any form of "advantage play" on roulette, allowed or not, would make that week's bonus your last.
The only casino I know offering this level of bonuses for VIPs is GNUF, but here the WR is the standard 30x, and other games count according to their weighting.
The 45x WR may be because they allow withdrawal at any time with loss of remaining bonus, rather than require the WR to be completed.
The best way to play this bonus would be on slots, as this would make sure you stayed on the VIP list for more than 1 week. If other games are played, they should be played with a bet in proportion to the level of betting on the slots, so if you are playing €10 spins, use €10 or €5 chips on roulette, rather than whacking €300 on Black and then switching to the slots grind after winning a couple.
There is also the risk that the casino just won't pay, citing "spirit of bonus". Unless accredited, there is a real risk of them getting away with it.
In order to advise better, we need the name of the casino (for experience), and the full terms, both general and promotional.
There are many cases where players believe a game that "doesn't count towards WR" can still be played, and only when they win do they find out it actually means the game is excluded on pain of winnings being confiscated..
To play this bonus, one should target slots that pay big from the bonus round, and hope to get a good one, or a few lesser ones close together. The downside is that if the slot is cold, the €1000 bankroll can disappear quickly without a bonus round in sight. Check for any max bet with a bonus rule, and stay well below this, even after a big win. Do not grind at a silly 9c per spin on Thunderstruck type slots after hitting something decent at €20 per spin elsewhere, this too could lead to a quick bonus ban.
Any strategy relies on you remaining eligible for this bonus every week for a decent length of time. Many casinos will remove a promotion this generous once a player hits big enough to achieve an overall lifetime profit.
