Placement of chips is done before any spin is triggered in roulette btc tables. Two controls are specifically designed to manage chips already on the board. Having a firm understanding of how each function works helps players manage their bets accurately before confirming a spin.

What does the undo button remove?

Undo removes the most recently placed chip. Each press of the undo button steps back one chip placement in reverse order. If a player placed three chips on three separate positions, the first undo press removes the third chip placed. A second press removes the second chip placed. A third press removes the first, leaving the board empty.

Some software tables extend undo to cover an entire chip stack placed in a single position in a single action. If a player used a repeated-click action to place ten chips on one number, undo in that context may remove all ten as a single step, or it may remove them one at a time, depending on how the software records the placement. The behaviour varies between tables and is typically visible after the first undo press. Undo does not affect chips placed in earlier sessions or chips from a previous round that were carried forward. It operates only on placements made within the current betting window. Once the spin is confirmed, undo is no longer available for that round.

What does the clear button do?

Clear removes every chip from the board in one action. Regardless of how many positions are occupied or how many chip values are in play, a single press of the clear button empties the entire layout. No confirmation prompt typically appears before the board is cleared, so the action takes effect immediately.

Clear removes all chip placements simultaneously, not in reverse order.

• Positions that were set up using the rebet function are also cleared if clear is pressed before the spin is confirmed.
• The clear button does not affect the chip value selector; the denomination in use remains set after clearing.
• Clearing the board does not reset the nonce or alter the current seed pair in any way.

When are these buttons available?

Both buttons are active only during the betting window. The betting window opens at the start of each round and closes when the player confirms the spin. Within that window, undo and clear can be used in any combination and any number of times. There is no limit on how many times either button can be pressed before the spin is triggered.

Once the player presses the spin or confirm button, the betting window closes. At that point, undo and clear become inactive for that round. The chip placement recorded at the moment of confirmation is the one the RNG uses to calculate the return, and no adjustment is possible after that point.

Rebet repeats the chip placement from the previous round. When a player presses rebet, the board fills with the same positions and chip values used in the last confirmed spin. After the reset is applied, undo and clear continue to function normally. Pressing undo after a rebet removes chips from the rebetted layout in reverse placement order. Pressing clear after a rebet empties the full layout as it would with any other arrangement.

This allows players to start from a previous configuration and adjust it rather than rebuilding the layout from scratch. A rebet followed by selective undo presses gives a quick way to modify part of a previous bet structure without removing the entire setup. The spin button remains inactive until at least one chip is confirmed on the board, regardless of how undo and clear are used beforehand.
