Locked Positions
Positions that persist their symbols across respins - core Hold & Win mechanic
Locked positions are grid positions that persist their symbols across respins. This is a core mechanic used in Hold & Win (H&W) bonus games.
Tag: locked:true
How It Works
During Respins
When a respin occurs (e.g., in H&W bonus):
- The respin executor checks each position for the
locked:truetag - Locked positions are skipped - their symbols are preserved
- Unlocked positions receive new symbols from the weighted distribution
During Payout
Locked positions fully participate in payout calculations:
- Their coin values are summed up
- Position multipliers are applied
- Grand Jackpot checks count locked positions

Example
Grid after H&W spin:
┌───┬───┬───┬───┬───┐
│ A │ B*│ K │ B*│ Q │ * = locked bonus symbol
├───┼───┼───┼───┼───┤
│ J │ 10│ B*│ A │ 9 │
├───┼───┼───┼───┼───┤
│ K │ Q │ J │ 10│ B*│
└───┴───┴───┴───┴───┘
After respin:
┌───┬───┬───┬───┬───┐
│ 9 │ B*│ Q │ B*│ B*│ New bonus landed!
├───┼───┼───┼───┼───┤ → Position locked
│ 10│ K │ B*│ J │ A │
├───┼───┼───┼───┼───┤
│ A │ J │ 10│ Q │ B*│
└───┴───┴───┴───┴───┘
