Overview
Open Face Chinese Poker can be abbreviated as OFCP. The goal of the game is to achieve more points than your opponent(s) by winning more hands also known as rows and/or by collecting royalties on premium hands without fouling.
 Each player plays cards across three hands, the top, middle, and bottom, such that at the end there are 3 cards in the top, 5 in the middle and 5 in the bottom; 13 total in the completed hand, legal or not.

Deal and Play
One player is designated dealer and deals 5 cards to each player, one at a time face down. The player to dealer's left now sets his or her 5 cards, placing them face up on the table, assigning each card to the front, middle or back hand. The other players do the same, in turn, ending with the dealer.
Once all players have set their first 5 cards, play continues clockwise, starting with the player on the dealer's left. Each player in turn draws the top card of the stock, exposes it, and adds it to one of his or her three hands. Once played, cards cannot be moved from one hand to another, and when a hand has its full complement of cards (5 in the back or middle, 3 in the front), no more can be added. When everyone has 13 cards, the hands are compared and scored.
The deal moves to the left after each hand.
Fouling/mis-setting

At the end of each round, you check the hand requirement for all players (by default Top hand ≤ Middle hand ≤ Bottom hand). If some player(s) don’t meet them, the hand is considered fouled/mis-set and has zero hand ranking. So if no players meet them, all players will score 0 for the round.
Variation: Pineapple

In Pineapple OFCP, instead of one card per round per player as in Original OFCP, each player is dealt three cards per round, playing two and discarding one. Recently, Pineapple OFCP is more popular than Original OFCP. Pineapple is the default setting option for OFCP in Board Game Arena.
Variation: 2-7 Lowball Middle
2-7 lowball middle is an option that can be selected before the game starts. If you use this option, then:
The middle hand adopts 2-7 lowball poker hand ranks. For hands to be valid, The bottom hand must be stronger than or equal to the top hand and the middle hand cannot be higher than 10 high.
In other words, in the middle hand:
You should only put in 2 to 10, and never put in J, Q, K, A; and the 5 cards should not form a straight, flush (same suit), and no pair or better. Otherwise your hand is invalid and you will lose this hand completely.
We want the middle hand to be as weak as possible, not as strong as possible.
Whether to use Variation: 2-7 Lowball Middle and whether to use Variation: Pineapple are options that can be set independently.
Scoring
For each line, top/middle/bottom, we compare the hand rank for each pair of players. The highest hand wins 1 point, plus the royalties of the hand, minus the royalties of the other player.
If one player defeats another on all three lines, he/she gets a bonus of +3 points.
The defeated player loses points equal to the gain of the other player. 
If one player loses all their 100 starting points, they lose immediately.
When using Variation: 2-7 lowball middle, top/bottom remain the same, stronger is better. In the middle hand, weaker hands are better. Weak hands beat strong hands.

Fantasyland
After normal scoring is complete, if any player has a pair of queens or better in the top line, they enter in fantasyland which is a bonus round where they receive 14 cards (13 cards in Original OFCP) and arrange them as they want. Remaining cards after completing a 13-card hand are discarded. On a fantasyland round, the other players play and points are scored as usual. The requirement to stay in fantasyland is higher, 3 of a kind/full-house/4 of a kind, for top/middle/bottom respectively.
When using Variation: 2-7 lowball middle, build KK or better in the top row and/or 75432(not the same suit) in the middle row to enter Fantasyland. To stay in Fantasyland, 3 of a kind in the top hand or 4 of a kind or higher in the bottom hand is required.
Progressive Fantasyland
Players receive one additional card for each hand rank above QQ when they enter Fantasyland (3 additional cards maximum). Remaining cards after completing a 13-card hand are discarded.
In Progressive Fantasyland Pineapple OFCP, in the top row: 14 cards for QQ, 15 cards for KK, 16 cards for AA and 17 cards for triplets(3 of a Kind). The player keeps 13 cards, discarding the remainder before setting the hands.
In 2-7 lowball middle, the condition changes into building KK or better in the top row and 75432 in the middle row with the same hand.
Royalties
If fouled/mis-set, no Royalties.
