==Game editions and differences==
The game was first published by Asmadi Games in 2010.

Then Iello published another edition of the game in 2011 with the same mechanics and card effects, but using a different terminology.

More recently, Asmadi Games gather the original game and all its expansions in a new box "Innovation Deluxe" with new graphics, and also made some slight modifications on nine cards for balancing purposes.

The online adaptation is based on the first edition of Asmadi games for the artwork. For the rules, you can choose between:

-'''Last edition''' (this is the default): these are the rules of the '''Asmadi "Innovation Deluxe"''' pack.

-'''First edition''': these are the rules of the '''original Asmadi game'''. These rules are consistant with the '''Iello edition too'''.

==Beginning of the game==
At the beginning of the game you have two cards of age 1 in your hand. You choose one to meld immediately and keep the other in your hand. The player who melded the first card in English alphabetical order plays first.
The first player gets only one action to start with, so does the second player in a four player game. After that, everybody gets two actions on their turn.

==Actions==
Except in the beginning, you must take two actions at your turn.
There are 4 possible actions. It is possible to select the same action twice:

'''DRAW:''' take a card of value equal to the highest top card on your board from the supply deck. If this deck is empty draw from the next available higher deck. This rule for drawing is also applicable for any effect with the "draw" keyword.

'''MELD:''' play a card from your hand to your board. It is played on the existing stack on the same color if it exists, otherwise this card starts a new one. Continue any splay if present.

'''DOGMA:''' each opponent with fewer of the feature icon (visible on their board) than you must execute the I demand effects. Each opponent with at least as many of the feature shares the non-demand effects. Effects are executed clockwise, finishing with you. If sharing an effect with one or several opponents has had ANY consequence on the game situation, take a single free Draw action at the end of your dogma action.

'''ACHIEVE:''' You can take an action to claim any available age achievement if you have at least 5 times the value of that age in your score pile AND a top card on your board of equal or higher value. For example to achieve age 1 you need 5 points and any card on your board. To achieve age 2, 10 points and at least a 2 as a top card and so on... Points are kept, not spent. Special achievements does not require any action to claim them and are won AS SOON AS the conditions are met.

==End of the game==
The game can end in three ways.

'''END OF GAME BY ACHIEVEMENTS:''' The game ends IMMEDIATELY (even inside a dogma effect) when a player got a required number of achievements:

-''2 players:'' 6 achievements

-''3 players:'' 5 achievements

-''4 players:'' 4 achievements

-''4 players '''(team game variant)''':'' 6 achievements combined by the teammates

'''END OF GAME BY SCORE:''' This happens if someone tries to draw an 11 or higher. The game end IMMEDIATELY (even inside a dogma effect). The winner is the player who has the greater score in his score pile. The number of achievements is only a tie-breaker. If still tied, the concerned players both win. In a team game, the teammates combine their score. If tied, they combine their achievements.

'''END OF GAME BY DOGMA:''' Some dogma effects of a few cards awards a win if some conditions are met. If more than one player are eligible (except teammates in a team game), the game continues.

==The golden rule==
'''Do as many as you can and ignore the rest.'''

This rule will help you to leverage ambiguities.

This has many consequences:

-Exchanges do not need to be symmetrical. According to the situation, 2 cards can be exchanged with 2, 1 card with 4, or even 0 card with 10...

-If you don't have enough card to fulfill the effect requirement, you process all what you have.

-However, if a "you may effect" proposes you return three cards and you don't have them, you CAN'T spend what you have to do what follows. You have to pass.

Senatorhung: /* List of 20 objectives */

===Completing objectives===

A player can only complete 1 objective at any time during each of their turns (until the final turn). They may do so if their objective card is matched by the conditions on the board at that time. Once an objective card is played, it is immediately replaced (if possible) with another objective card from the purple deck. A completed objective is never lost.

Beware .. there are certain cards which will allow opponents to steal cards from your hand, or specific items from your collection (hunting tokens can not be stolen). Each player can have a maximum of 2 objective cards in hand (except for the player who finds and plays a specific card to be able to hold 3) - any objective cards above the hand limit must be returned to the purple deck.

===List of 20 objectives===

Senatorhung: /* REQUIREMENTS OF A COMPLETE AUTOMOBILE */

It is 1888, and everywhere you turn, people are talking about the horseless carriage. The players build an automobile prototype by patenting new parts, scavenging in the junk yard, and looking for opportunities to trip up their fellow automotive pioneers, all the while seeking to impress investors that are looking to get into car production. Gear & Piston is a simple, yet engaging 30-60 minute game for 2-6 players.
===QUICK RULES REFERENCE===
====ROUND SEQUENCE AND PHASES====
*I. Place action tokens.
(between I and II, you may discard ONE blueprint)
*II. Resolve actions.
*III. Refresh Patent Office (Location #3) and Junk Yard (Location #4).

====LOCATION ACTIONS====
*Back Alley (Location #2): *WARNING* The Action Token placed in the Back Alley cannot be used during the next planning phase.
** Choose 1 action from the following.
<OL>
<LI>Black Market (draw 3 New Parts and keep 1),</LI>
<LI>Espionage (look at one player's blueprints and take one of them),</LI>
<LI>Union Muscle (move an Action Token ahead in another location).</LI>
</OL>
*Patent Office (Location #3): Take 1 New Part, either from the face up parts or from the top of the stack. You can only hold a maximum of 5 blueprints in hand, so if you already have 5 blueprints, any further Patent Office actions are wasted.
*Junk Yard (Location #4): Take up to 2 Junk Parts, either from the 3 face up parts or from the top of the stack. If a face up part is chosen, it is replaced before the second is chosen. You can only hold a maximum of 5 blueprints in hand, so if you already have 5 blueprints, any further Junk Yard actions are wasted.
*Workshop (Location #5): Actions that may be used are Build, Dismantle, and Upgrade. The FIRST action token placed in this location provides for 3 workshop actions. The SECOND action token placed in this location provides for 2 workshop actions. Every further action token at this location will only allow 1 workshop action. The last player to place an action token here will be the first player to act in the next round.

====REQUIREMENTS OF A COMPLETE AUTOMOBILE====

You start out building your automobile in 2 sections - the front and the back. At the end of the game, the 2 sections will be joined together.

* Each automobile requires at least:
<UL>
<LI> at least ONE engine (consists of a motor and at least one fuel tank of the same color);</LI>
<LI> at least ONE Gear;/LI>
<LI> at least TWO Axles; and/LI>
<LI> exactly ONE steering mechanism./LI>
</UL>

Further Building Notes:
* Every motor requires a matching fuel tank but there can be extra fuel tanks.
* Colored improvements and fuel require an motor of same color.
* Each part on the top row requires a part on the bottom row and vice versa.
* All parts must be supported by an axle. Each Axle supports only the five parts surrounding it (3 above, 1 on either side).
* There are bonus points at the end of the game for each player for their longest contiguous chain of parts of the same colour.

====GAME END====
*There are not enough tiles to refill a location from the refill Stack.
OR
*One of the players has a complete automobile with at least twelve parts on it.

At the end of the game all players must join the two halves of the car and have a complete automobile. Players may need to complete their automobile by adding scrap. Illegal parts must either be covered up or have scrap added to make them legal. Each scrap acts as a single part. In the top row it can be a motor, fuel or steering. In the bottom row it can be an axle or a gear. The smallest complete auto is 6 pieces. Do not keep adding scrap to your vehicle if it would make your car longer than 9 or you risk crashing the game. If your car is that long and is incomplete there is an illegal part that must be covered up.

====SCORING====
* VP according to Investors
The first investor cares about the number of each icon. If there are 0 or 1 of range, comfort or power it is worth no points. The first two range are worth 2 or 3, first two power and first two comfort are worth 1, 2 or 3, based on the investor's preference and each additional is always worth +2 VP regardless of the investor's preference.
* +1 VP for each part of the same color (red, green, yellow or grey) in the largest continuous section. Each car will have at least 4 grey parts so its likely to be the dominant color. Scrap parts have no color.
* -1 VP for each point of Volatility not countered by a wrench icon.

====BEGINNER TIPS====
* Keep an eye on what other players are doing. If three people are building the same color of engine it is going to be very hard for all of them to succeed.
* Make sure to build often enough because you can hold a maximum of 5 blueprints at a time. Also if you aren't in the first two spots in the workshop you aren't going to get enough actions to finish your car.
* It is advisable to visit the Junk Yard every now and then especially if there are some parts without Volatility for grabs. The junk yard also has only the 5 kinds of parts required to finish a vehicle so if you are missing a key part you are much more likely to find it here than blindly drawing from the patent office.
* The game can end surprisingly fast and each Black Market action and blind draw from the Patent Office makes the game end even faster.
* Remember that you can upgrade multiple junk parts with one workshop action.
