Many players mistakenly believe they can place a marker chip on a space that is already occupied by another player's chip.
No, according to the Sequence Official Rulebook, you cannot place a marker chip on a space that is already covered by another marker chip.

These rules correspond to the US edition of Sequence.
Official Rule Breakdown
Regarding the placement of chips on occupied squares, the official rules state that each card is pictured twice on the game board. A player can play on either one of the card spaces as long as it is not already covered by another marker chip. Once a marker chip has been played, it cannot be removed by an opponent except when using a one-eyed Jack. This rule ensures that once a space is claimed, it remains occupied unless an anti-wild Jack is played.
Step-by-Step
- Step 1: Select a card from your hand.
- Step 2: Place the card face up on your personal discard pile.
- Step 3: Locate one of the two matching spaces for that card on the game board.
- Step 4: Check if the space is already covered by another marker chip.
- Step 5: If the space is open, place your marker chip on it.
Example Play Situation
Alice plays a 5 of Hearts and places her blue chip on one of the two available 5 spaces. Bob then plays a 5 of Hearts, but since both spaces for that card are already covered by Alice and another player, Bob must declare it a Dead Card.

Common Misconceptions
- Thinking you can stack two chips on one space
- Believing you can play a card on an occupied space to complete a sequence
- Assuming a one-eyed Jack can remove a chip that is part of a completed sequence
