bet365 are putting $100,000 up for grabs for any member who correctly selects the winners of six designated races each Saturday.

$100,000 on offer for this week's bet365 Pick 6 Challenge 

After three lucky bet365 members shared the $75,000 spoils in last weekend's Pick 6 Challenge the leading bookmaker has upped the ante to $100,000 this Saturday. 

The whopping prize pool will be split between any logged in customers who correctly select the winners of six designated races. There's a consolation pool of $10,000 to be split between anyone who selects five of the six and $5,000 to be shared with those who 'only' pick four winners. 

This Saturday will feature the following races, and the R&S team has narrowed it down for you with the following selections. 

Flemington Race 4 - Racing and Sports Rising Fast Stakes - 2.20pm 

Triple Missile  (5) looked to be travelling very well first up in the G2 Gilgai but just found Star Patrol a touch too strong late. That's excellent form for this level and if he runs up to that he'll take beating with McDonald on. SPACEWALK (7) came home in some big late splits over 1000m at Caulfield last time when beaten. Interesting to see him at 1200m but drawn wide, down the straight looks a nice scenario for him. IT'SOURTIME (4) gets back to his favoured straight track after racing in Sydney last start. Prior to that he was fourth to Star Patrol which ties in with Triple Missile. C'EST MAGIQUE (9) also has Star Patrol form but then dropped right out over 1400m last start. She can improve. CHAIN OF LIGHTNING (2) was good behind Asfoora first up and 1200m suits better but she does have to concede weight to some handy males. 

Rosehill Race 6 - Four Pillars Midway - 3.20pm 

Oakfield Arrow  (5) consistent mare set to peak third-up. Covered ground with the 59kg when a close-up fourth over 1400m at Randwick on October 21. Drawn to stalk the speed and has a good record this track. BACKROWER (10) has disappointed this time in but worth another chance today from the good gate. Having fifth start here and has the ability to take this out on best form. MODERN MILLIE (19) tough mare who comes out of a strong race when resuming to run third behind FALL FOR CINDY over 1400m at Warwick Farm on October 11. Maps well and not to be underestimated. SMARTAWI (14) raced in better races last time in and caught the eye first-up when 13th over 1400m at Randwick on October 21. Look for him late with the good early tempo.

Flemington Race 6 - Coolmore Stud Stakes - 3.40pm 

The G1 Coolmore Stud Stakes. Keen on Cylinder  (2) who ran very well in The Everest last start, more than holding his own against some of the best sprinters in the world. He's been the benchmark colt all the way through and if he holds his form he should be winning. KING'S GAMBIT (5) is the x-factor. He's clearly got talent and was impressive last start but whether the straight and big field bring him undone remains to be seen. SHINZO (1) hasn't been beaten all that far in the Golden Rose and The Everest but he's capable of improving and being a Slipper winner, his best would go close. STRETAN ANGEL (18) has done nothing wrong and is proven down the straight. I AM UNSTOPPABLE (10) should be thereabouts again.

Rosehill Race 8 - James Squire Golden Eagle - 4.45pm 

Osipenko  (7) tough entire who comes out of a strong form race when third to MR BRIGHTSIDE in the G1 Makybe Diva two back at Flemington. Three weeks between runs when a plugging tenth behind GOLD TRIP over 2000m in the G1 Turnbull Stakes at latest. Recent tick over trial has him spot on for this. Queensland Derby winner KOVALICA (5) has a sense of timing third-up after making up good ground late when fifth over 1600m in the G1 King Charles III Stakes at Randwick last time out. Will go back again from the poor draw but good early tempo should see him motoring late. AMELIA'S JEWEL (16) smart WA trained mare who turned in the worst run of her career when ninth over 1600m in the G1 Toorak Handicap at Caulfield on October 14. Damian Lane retains the ride and maps well for this. HAWAII FIVE OH (1) finished third in the Stradbroke Hcp last prep and three runs back have been full of merit. Rawiller back aboard and gets every chance to run the 1500m out from the good gate.

Flemington Race 8 - Empire Rose Stakes - 5.00pm 

Alcohol Free  (1) gets to the mile fourth up from a spell which looks to suit as a dual G1 winner over the trip overseas. She ran her best Australian race last start in The Invitation when fourth, beaten 0.7 lengths by Espiona and looks to get the perfect run behind a good speed here. ATISHU (4) had no hope back in the field in the G1 King Charles III last start. She was very good in this race last year and will be storming home off a strong tempo. HOPE IN YOUR HEART (3) doesn't know how to run a bad race and with any luck from the inside gate will be in the finish. WISHLOR LASS (14) keeps raising the bar and will be rock hard fit on the back up. PRINCESS GRACE (2) was disappointing considering her SP last start but can bounce back.

Flemington Race 9 - The Damien Oliver - 5.40pm 

Tamerlane  (5) was given a perfect ride to lead all of the way over this track and distance last start when backed off the map and he should be able to hold the front again here. More depth, but he's a pretty bombproof horse who will give a huge sight. At big odds, KING MAGNUS (2) is worth something. He's first up from a short spell here but loves this track and distance and typically goes well fresh. Can see him getting a good run midfield and sneaking into the finish. HERE TO SHOCK (10) found the G1 Toorak Handicap a bit tough last time without a great run. Second to Antino prior reads well and he draws well here. VILANA (1) looks better suited out to 1400m and his best figures would go a long way to winning this. It'd be fitting for Olly to win the race named in his honour. AYRTON (4) was back to his best first up but he can often drop off second up.
