HAS:RTB is a multiplayer game expansion to the HAS: Shortform. HAS:RTB simulates what it’s like to “Demand Side Platform" (DSP).
Just like in the real world, the DSP (you) bids for the chance to serve ads in realtime against other DSPs (the other players). The objective of the game is to make the most advertising money.
If you are familiar with HAS: Shortform, the gameplay is similar. The biggest difference with RTB is you will first need to win an auction against other players for each request card before you can serve an ad against it.
Just as with HAS: Shortform, whenever you draw an Ad Placement, look at the top two placement cards and select one. Then put the other card on the bottom of the Ad Placement deck.
The game ends when all each ad request has been auctioned off.
Note: Unlike Shortform, the Duration on the Placement Card is ignored in HAS:RTB
Each is resolved as a second-bid auction like this:
Corner case 1
If the top two bids are the same amount, the winning bidder pays that price. This comes up when two or more players tie for highest bid
Corner case 2
If only one player bid for the ad request, the winning bidder still pays 1 chip (not zero. Nothing is free!)
Corner case 3
If no one bid, discard the ad request
The winning player "serves" the ad to one of their placements that match the targeting criteria of the request (see HAS: Shortform for more detail).
reveal the placement and place it into your scoring pile face up. Then draw a new placement to replace the one that scored (using the draw 2, keep one method).
When revealing a completed placement, if the Ad Requests do not match the Placement's Targeting, the advertiser refuses to pay and the Placement counts as zero points.
just keep track of which placement you delivered it to by putting the Ad Request card behind the Placement (both hidden).
After all ad requests have been auctioned, your game is complete. Each player adds up the monetary value from the placements they completed with matching Ad Requests during the game. Whoever has the highest score wins.
If more than one player ties for the highest score, there is a fight to the death amongst ALL the players...unless players can elect a winner peacefully.
