Hold & Next Queue

Last updated Apr 7, 2026

Hold Piece

Press the Hold key (default: C) to store your current piece for later use.

Rules

  • When you hold a piece, you receive the next piece from the queue (or the previously held piece)
  • You can only hold once per piece - after holding, you must place the new piece before holding again
  • The held piece is shown in the Hold panel on the left side of the board

Strategy

  • Hold I-pieces for Quad opportunities
  • Hold T-pieces for T-Spin setups
  • Use hold as an emergency escape when the current piece does not fit well

Next Queue

The next 5 pieces are displayed in the preview panel on the right side of the board.

7-Bag Randomizer

Pieces are generated using the 7-Bag system:

  1. All 7 pieces (I, O, T, S, Z, J, L) are placed in a bag
  2. The bag is shuffled randomly
  3. Pieces are dealt one at a time from the bag
  4. When the bag is empty, a new bag of all 7 pieces is shuffled

This guarantees:

  • You will see each piece at least once every 7 pieces
  • The maximum drought for any piece is 12 (last in one bag, first in the next is 13 apart, but you see it at position 7 and then at position 20 at worst = 13 gap, meaning max 12 pieces between)
  • No truly unfair RNG streaks
