Overview
Try to figure out your hand whilst battling your opponents to gain the most gems first!
Core Concept
Some of your hand cards are known only to you, and other hand cards are known only to everyone else
Turn
On your turn, you either ask for information or challenge someone
If you ask for information, pick one of your cards you cannot see and first say whether you know anything about it, if you know nothing then you can be told either element (colour) or power level (number) and it's up to the others to pick which to tell you. However, if you already know one of these features, the others must tell you the unknown feature i.e. if you already know the number, they can't tell you the number again
Exception 1: if it is a special (*) card, regardless of its features, the others can only say it's a special and not the features
Exception 2: If what you think you know is misremembered and wrong, this will not be corrected for free, but it's up to the others whether to clue the truly unknown feature or whether to clue the incorrectly understood feature
Exception 3: If the feature clued about can be found on other cards in your hand, you must also be told this (including for special cards)
Alternatively, you can choose to challenge someone
This challenge can be either element or power level based, decided by the challenger
Before the challenge begins, the challenger must give information to the opponent following the above information rules
Each in the challenge simultaneously pick a card (private or public) to use
If this is an Element challenge, Water beats Fire, Fire beats Plant, Plant beats Water, Light wins, Shadow loses
If this is a Power Level challenge, the highest number wins
Whoever wins gains 1 gem
If it's tied, play again with remaining cards in hand but keeping the same feature (element or power level)
Winning a tied round gains 1 extra gem
If needed, take another tied round, and increase the winning gems by 1 for each time (3rd round = 3 gems at stake
Once a challenge is resolved, the two contestants draw back up to 4 cards (the winner takes their cards blind and facing the group, the loser takes their cards privately facing themselves)
Game End
The game can end in two ways
If during a challenge the opponents tie on ALL their hand cards, the game immediately ends with a win for everyone! (or no one!)
Otherwise, the first to 7/6/5/4 gems in 2/3/4/5 players, wins!
