A very dumbed-down, simplistic hypothetical:
You're offered $10,000,000 to help your grandma become the top 0.25% of the player pool in either Hearthstone or NLHE.
In Hearthstone, this means achieving the rank of Legend(at least according to Blizzard, no idea if anyone who plays just one game per month qualifies and such).
In poker, your grandma would need to be winning 0.01bb/100 on a sufficient sample. I looked at the current NLHE lobby on Stars and counted the players per limit.
Rough numbers:
Stake | Players | Percentile |
---|
$0.01/$0.02 | 5171 | 100.00 |
$0.02/$0.05 | 2517 | 66.35 |
$0.05/$0.10 | 2806 | 49.97 |
$0.08/$0.16 | 338 | 31.71 |
$0.10/$0.25 | 2012 | 29.51 |
$0.25/$0.50 | 1075 | 16.42 |
$0.50/$1.00 | 736 | 9.42 |
$1/$2 | 390 | 4.63 |
$2/$4 | 80 | 2.10 |
$2.5/$5 | 53 | 1.57 |
$3/$6 | 78 | 1.23 |
$5/$10 | 52 | 0.72 |
$10/$20 | 33 | 0.38 |
$25/$50 | 13 | 0.17 |
$50/$100 | 5 | 0.08 |
$100/$200 | 4 | 0.05 |
$200/$400 | 4 | 0.03 |
The top 0.25% player is currently seated on a 2000NL table.
Which route do you choose to give your grandma the best chance at winning the 10 million?
Since the method can be argued against in a variety of ways, I'd choose HS even over something like 25NL so it's not exactly close.
