Access Configuration

Use the access property to control which game surfaces users can access — and why they are blocked when they can't.

Basic example

MindtrainingPlatform.init('mindtraining', {
  access: {
    games: {
      crossword: {
        default: {
          playToday: true,
          playArchive: false,
          viewStatistics: false,
          saveState: true,
          blockedReason: 'subscription_required',
        },
      },
      sudoku: {
        default: {
          playToday: true,
          playArchive: true,
          viewStatistics: true,
          saveState: true,
        },
      },
    },
  },
})

Access policy properties

Each game entry has a default policy, and an optional variants map for per-variant overrides.

Property	Type	Default	Description
playToday	boolean	true	Allow playing today's game
playArchive	boolean	true	Allow browsing the archive
viewStatistics	boolean	true	Allow viewing the game's statistics page
saveState	boolean	true	Allow saving and resuming game progress
blockedReason	string	—	Reason shown when access is denied (see below)
blockedReasons	object	—	Per-surface blocked reasons (overrides blockedReason)
meterLimit	object	—	Limit the number of game starts in a rolling window
levelLimit	object	—	Limit access above a certain difficulty level

Blocked reasons

Value	Meaning
"login_required"	User must log in to access
"subscription_required"	User must have an active subscription
"variant_locked"	This game variant is locked
"host_rule"	Blocked by a site-level business rule

Per-surface blocked reasons

If you need different messages for today's game, the archive, or statistics, use blockedReasons:

crossword: {
  default: {
    playToday: true,
    playArchive: false,
    viewStatistics: false,
    blockedReasons: {
      archive: 'subscription_required',
      statistics: 'login_required',
    },
  },
}

Meter limit (metered paywall)

Allow a limited number of free game starts within a rolling time window:

crossword: {
  default: {
    playToday: true,
    playArchive: true,
    meterLimit: {
      maxStarts: 5,      // maximum game starts allowed
      intervalDays: 30,  // rolling window in days
    },
    blockedReason: 'subscription_required',
  },
}

What are variants?

A variant is a version of the same game type with different content categories or characteristics — same rules, different flavour. For example, crossword may have variants like mini (a smaller grid), kids (simple vocabulary), or sports (sports-themed clues). Each variant shares the same game engine but is treated as a separate access surface.

Variants are identified by a string ID configured on the platform side. When no variant-specific policy is defined, the default policy applies to all variants of that game.

Variant-level overrides

Apply a different policy to a specific variant while keeping default for everything else:

crossword: {
  default: {
    playToday: true,
    playArchive: false,
    blockedReason: 'subscription_required',
  },
  variants: {
    mini: {
      // The mini crossword is free — override the default
      playToday: true,
      playArchive: true,
    },
    kids: {
      // Kids variant requires login but not subscription
      playToday: true,
      playArchive: false,
      blockedReason: 'login_required',
    },
  },
}
