Retro Achievements Guide
🔶 Single Ennead _^(Arduboy)

Single Ennead is a port of the popular Triple Triad minigame from Final Fantasy VIII. The game is played on a 3x3 grid with each player choosing 5 cards to include in their hand. Each card has 4 values indicating the power level of each side in clockwise order: Up, Right, Down, Left.

The players take turns placing cards on the grid from their hand. If a card is placed next to another card, the adjacent power levels are compared. If the attacker's power level is higher, it will capture the opponent's card. Once the grid is filled, the player with the most points wins the match and earns one of their opponent's cards.

Tip

Since there is no restriction on which cards you can purchase, the easiest way to win rounds is to purchase the absurdly powerful card #100. The card costs 52000 gold but it has As on all sides and will make most matches trivial to win.

Play a few matches to earn gold and new cards. The game can be reset if you are losing a match to avoid losing a card.
Pay the Queen of Cards 500 gold to change the rules until you get a good ruleset.
Earn 52000 gold and purchase Card #100
Use the powerful cards to earn new cards and climb the ranks. - Purchase cards 96-99 to build your final deck
Purchase all remaining cards and do any achievement cleanup that you didn't get along the way.

Win: Lowest - Allows you to bring all high level cards and one cheap low level card which you can purchase for $1 if you lose it. Not super important because you can reset before losing if the match isn't working out in your favor
Payout: 4x (IMPORTANT) - The most important rule for earning $. Multiplies your earnings
