The IHG Big Win presents each IHG Rewards Club guest with a customised set of "goals" to meet in order to enjoy a huge payout. Some of these bonus payouts are over 100,000 points.

In my case, I was presented with a pretty lacklustre set of offers with a total potential payout of only 31,000. My set of offers is summarised as follows:

1 night win - 1,000 Points
Stay 4 nights - 3,000 Points
Book 2 stays with IHG directly - 2,000 Points
Stay at 3 different IHG brands - 7,000 Points
3 Saturday nights - 8,000 Points
Big Win - 10,000 Points
Total - 31,000 Points

As such I have initially decided not to participate in this round's Big Win offers.

However, since I only need one additional stay to earn 27,000 points (on top of base earnings), I have decided to participate in the Big Win despite it being relatively uninspired. Essentially 3 stays will gain me 28,000/31,000 of the potential bonus points.

Singapore Reward Nights Redemption
(Rates in S$ have been selected on a day that typically does not reflect peak demand prices.)

Holiday Inn Express: Singapore Clarke Quay - 20,000 Points (S$180++)
Holiday Inn Express: Singapore Orchard Road - 20,000 Points (S$207++)
Holiday Inn: Singapore Atrium - 25,000 Points (S$163++)
Holiday Inn: Singapore Orchard City Centre - 35,000 Points (S$256++)
Crowne Plaza Changi Airport - 40,000 Points (S$234++)
Intercontinental: Singapore - 50,000 Points (S$267++)

As shown in the list above, the points required for a free night do not always correlate positively to the price of room. Since the ceiling for reward nights redemption in IHG is 50,000 Points, there are some properties in the world that offer rooms/villas that typically sell for almost S$1,000 at this rate (e.g. InterContinental Bora Bora Resort & Thalasso Spa Hotel). Therefore, it is always good to conserve IHG points for more expensive properties in order to get more bang for the buck.
