Bold time

The bold time is an official term for the highest reported time that has been achieved on any specific level, though not always the quickest possible time. If the bold time is known to be capable of improvement, the higher time is known as the Melinda time.

Bold rules

All the bolds are recorded by who collected them first, and then second, the latter of which is known as a confirmation. A time held by only one player is known as unconfirmed. A partial confirm can occur when an unconfirmed bold breaks a previous bold record by at least two seconds, if a second player obtains a time higher than the previous confirmed record but lower than the unconfirmed record. For example, if the previous bold record were 353 and a player obtained an unconfirmed time of 355, a second player achieving 354 would be a partial confirm.

Joint bolds

By special agreement between two or more players, usually as a result of side-by-side work on the same record, a bold may be reported as joint, meaning credit is shared. On David Stolp's site, a joint bold is recorded if more than one player sets the same record within 30 seconds of each other, regardless of normal criteria for joint bold scores. A joint bold automatically counts as a confirmation, since two people have scored it. The earliest joint bold was set on April 11, 2002, as the bold on Zartacla.

Untimed levels

On levels without a time limit, such as the 29 that are in Chip's Challenge 1 (but none in CCLP2), a separate time is kept aside from the official scoring that is counted as if the time limit were 999. This is often known as a T-Chip time, in reference to the Ruben Spaans program that automatically set all levels in a set to this time limit. Therefore, a T-Chip time for a level that took 645 seconds to complete would be 354.

Tile World automatically records the T-Chip time as it would any other time, but since there is no time displayed on the display, it is difficult to tell how much time it actually took. (Should an untimed level have a time limit added to it, or the time limit change, the time will automatically adjust itself to the new time limit.)

CC1 (MS) unconfirmed bold times, with time limit

• 436 - Blobnet, held by J.B. Lewis. 434 had been held unconfirmed since January 2003 by Pekka Lassila; beginning in April 2009, Andrew Bennett developed the earliest advanced stages of the level's quick play and ran to confirm this time. 431 and 433 fell in quick succession, and on April 28, Andrew famously confirmed the 434 time with a .8, such that if his precautionary spring step in front of the exit had worked properly, a 435.0 time would have resulted. 435 was not duplicated until November 2, by which time the extensive work done, perhaps the most in-depth analysis of any level in the entire 447 contiguous, later allowed for John to extend the unconfirmed bold out to 436 (a time which in 2004 would have been unforseeable).
• 717 - Block Buster II, held by David Stolp. The previous confirmed bold record was 714, which stood for over 16 years.
• 717 - Cake Walk, also held by David Stolp. The previous record was 712.

CC1 joint bolds

No CC1 joint bolds exist; the joint bold was introduced in April 2002 as noted above. Most CC1 records were taken at this time; out of the over 650 CC1 records set in total to date, only 50 to 60 were set after the release of CCLP2, with roughly 15 of them on timed levels. One 618 score on Mind Block may or may not have been reported before CCLP2; its exact date is unknown.
