Bots are the heart of the game. They have several stat values, including: attack, defense, critical hits, barriers, and special abilities that activate under certain conditions. These Bots make up your Battle Deck for the Battle Phases.
The Bot card's attack value is at the top of the card. When the Bot is in attack position, you place it so that the attack value points towards the other players.
The defense value is on the left side of the card. When the Bot is in defense position, you much turn the card sideways so the defense value is pointing towards the other players.
You can add Bots to your deck by building them, choosing from those available in the Laboratory and paying their cost with Scraps. You can also recycle them to obtain additional scraps, which can be used to build other Bots.
Bots are divided into four tiers. The higher the tier, the greater the power of the Bot. to build higher tier Bots, you need to upgrade your workshop.
Each Bot has a name and belongs to one or two of the following factions: Animal, Appliances, Bio, Steam, Mech, Warfare.
Contraptions are a particular type of Bots, capable of expanding your strategies with powerful abilities, but only under specific circumstances.
Unlike other Bots, Contraptions have no attack or defense value. They contain no critical hits or barriers and belong to no faction. These cards are not part of your Battle Deck. They always remain face up in front of you after they are built. They are never shuffled into your deck.
When a Contraption card is upright, it is enables and available for use. When used, the card must be rotated to the side, which indicates that the Contraption is unavailable and cannot be used until it is turned upright again.
The Laboratory is the cental game board for Rumblebots. It holds Bots of all tiers and shows which ones can be built.
As individual player's level up their Workshops, new tiers of Bots become available to be built, in new rows. The first player to level up their Workshop will reveal a new tier of Bots in the row above the previous tier. That new tier of Bots is only available to a player once they have leveled their Workshop up to the correct tier level.
At the bottom left of the Laboratory lies the Recycling Area. When a Bot is trashed for whatever reason, put it here, face up. Recycling and Trashed are specific actions and effects. Cards that are Discarded during the Battle Phase are not placed here. They go in a personal discard.
On the left of the Laboratory there is the Round Tracker. The game plays over the course of 6 rounds. Five standard rounds and one final Showdown round. The round track also shows which direction that play passes during each round, alternating clockwise and counter-clockwise turns. This track also holds the crystals that are awarded each round.
Scraps are the game currency. Each player keeps track of their scraps using a marker on the relevant track in their Workshop. When you earn or spend scraps, move the marker forward or backwards, accordingly.
The first part of the Build Phase is an income phase, in which players recieve scraps equal to the number of the round. Ex. 1 Scrap in Round One, 2 Scraps in Round Two, etc.
The Scrap marker is reset to 0 at the end of a player's Build Phase. Scraps cannot be kept between rounds.
Crystals are gained by winning Battles or thanks to some Bots' abilities. They are used for:
- Obtaining additional Scraps.
- Drawing Bot cards from the Laboratory decks.
- Activating specific Bot abilities.
Additionally, Crystals can trigger an early win condition and give behind players an Underdog bonus.
Dominance Victory: If, at the end of any Build or Battle Phase, before the Showdown, a player owns at least 6 crystals more than each of the other players, you immediately win the game!
Underdog Bonus: At the start of your turn, if you have at least 2 crystals less than the player who has the most, you recieve 1 additional scrap. In the 1st round, this bonus is not available.
The Workshop tier determines the highest level of Bots that you can build.
The Scrap track indicates how many scraps you have available to spend.
Store any crystals you get in your Storage, the purple zone.
From there, crystals can be used by energizing them to move them to the Reactor, the orange zone, to get bonuses.
After each Battle, the energized crystals go into the Cryo-cell, the blue zone, from which, under certain conditions, they may return to your Storage.
