Custom JavaScript constraints

Create constraints between pairs of cells by providing a custom JavaScript function.

Name:

Chain handling :

// Return true if the cell values a and b are // a valid pair. // Example: a < b (thermometer constraint)

constraintCheck = (a, b) =>

Define a finite-state machine using JavaScript transition and accept functions. The constraint will be satisfied the state-machine reaches an accept state after processing the cells in order.

NUM_CELLS is available as the number of currently selected cells.

Tip: You can use console.log to debug your state machine.

Name:

Unified input

// The initial state(s). States can be any // JSON-serializable value, except arrays. // Use an array for multiple start states.

startState = ;

// transition takes the current state and // cell value and returns the next state, or // an array of states. Returning undefined or // the empty array generates no next states.

function transition(state, value) { }

// accept returns true when the state is a // valid final state.

function accept(state) { }

// Max depth for state creation (optional).

maxDepth = ;
