Overview

Pendulum is a turnless real-time worker-placement strategy game where players are nobles vying to succeed the Timeless King as ruler of Dunya. Players simultaneously place workers on action spaces timed by sand timers, managing their time as a resource across three different action areas. The game runs in real time except during periodic Council phases. The player who best manages four victory tracks (Power, Prestige, Popularity, and Legendary Achievement) wins.

Components

Setup

  1. Place the game board (correct side for player count) centrally.
  2. Place the council board nearby.
  3. Place the 3 sand timers on matching-color action areas in the top-row gold circles.
  4. Shuffle achievement cards; reveal the top one with the legendary achievement token.
  5. Shuffle province cards; deal 4 face up to the display.
  6. Each player takes their character’s stratagem cards, player mat, 3 common workers, 2 grande workers, 4 VP tokens, starting resources, and starting province cards.
  7. Place VP tokens on starting positions of the 4 victory tracks.

Turn Structure

Pendulum has no turns during the action phase. Players act simultaneously in real time. The game alternates between:

Action Rounds (Real-Time)

All players act simultaneously. When a sand timer runs out, any player may flip it, unlocking the workers on the now-uncovered row and locking workers on the covered row:

  1. Place workers on open action spaces (top row when timer is up, bottom row when timer is down).
  2. Retrieve workers from spaces that have been timed (the timer has flipped over them).
  3. Execute the action of the space when retrieving a timed worker.

Council Phase (Turn-Based)

After a set number of timer flips, the Council phase triggers:

  1. All action stops.
  2. Players may retrieve any remaining timed workers and resolve their actions.
  3. Play council reward cards and resolve council voting.
  4. Advance victory tracks based on council results.
  5. Reset for the next round.

Actions

The three action areas correspond to the three timers:

Timer Color Duration Action Type
Green 45 seconds Quick actions (gain resources, basic moves)
Black 2 minutes Medium actions (provinces, stratagems)
Purple 3 minutes Long actions (major strategic moves, achievements)

Scoring / Victory Conditions

The game ends after the final Council phase (typically 4 rounds).

To win, a player must meet the minimum threshold on all 4 victory tracks. Among players who meet all thresholds, the player with the highest legendary achievement wins. If tied, the player with the most votes wins.

Players who fail to meet any threshold cannot win regardless of other track positions.
