Nerdy Inventions

We are a group of nerd inventors. In this competition, who can invent the most prolific inventions and become the nerdiest inventor?

Nerdy Inventions (発明オタクの怪奇な傑作) is a game for 2-4 players that takes about 25-30 minutes. Players take turns until the game meets one of the ending conditions.

In each turn, the active player rolls 3 dice. Then he may do the following 4 actions as many times as he wants (the actions can be done repeatly). When he cannot or decide not to take any more actions, he passes and next player's turn begins. The 4 available actions are:

 Use your own invention card
 Charge your own invention card
 Research (Swap uninvented cards)
 Build (Take) invention card

Invention cards provide victory points and abilities. At the end of the game, the player with the highest total of victory points wins the game!
