===Cyber Blader===
Originally, the "3 monsters" effect of "[[Cyber Blader]]" could negate Continuous Effects, leading to the possibility of infinite loops. This had been fixed was addressed in the ''OCG'' as of with the erratum issued in ''[[Dimension Box Limited Edition]]'', but persisted for several more years in the ''TCG'' until it the same erratum was brought back in line issued in ''[[Speed Duel GX: Duel Academy Box]]''.
====Voluntary====
Player 1 [[control]]s three monsters, one of which is [[owner|owned]] by Player 2, but being controlled by Player 1 due to "[[Snatch Steal]]".
* Since Player 1 controls three monsters, the effect of "Cyber Blader" negates the effect of "Snatch Steal". The equipped monster returns to Player 2's control.
* Since Player 1 now controls two monsters, the effect of "Cyber Blader" instead doubles its ATK. The effect of "Snatch Steal" is no longer negated, so Player 1 gains control of the equipped monster.
* The above sequence would repeat infinitely, with the player who controls the monster equipped with "Snatch Steal" never settling.
'''Old Ruling:''' Player 2 is was not allowed to Summon "Cyber Blader".
'''New Ruling:''' Whichever card is was identified as the cause will be would have been sent to the Graveyard by [[game mechanics]].
====Involuntary====
Player 1 [[control]]s two monsters, one of which is [[owner|owned]] by Player 2, but being controlled by Player 1 due to "[[Snatch Steal]]". Player 1 also controls "[[Jam Breeding Machine]]". Player 2 controls "Cyber Blader".
* Since Player 1 controls three monsters, the effect of "Cyber Blader" negates the effect of "Snatch Steal". The equipped monster returns to Player 2's control.
* Since Player 1 now controls two monsters, the effect of "Cyber Blader" instead doubles its ATK. The effect of "Snatch Steal" effect is no longer negated, so Player 1 gains control of the equipped monster.
* Since Player 1 now controls three monsters, the effect of "Cyber Blader" negates the effect of "Snatch Steal". The equipped monster returns to Player 2's control.
* The above sequence would repeat infinitely, with the player who controls the monster equipped with "Snatch Steal" never settling.
'''Old and New Rulings:''' Since the loop cannot could not be avoided, whichever card is was identified as the cause will be would have been sent to the Graveyard by [[game mechanics]] (no official ruling was issued, but it would have likely been either "[[Snatch Steal]]" or "[[Cyber Blader]]").
===In video games===
Certain video games may implement their own rulings for infinite loops, or fail to recognize them leading to a crash{{fact}} or a softlock.
For example, ''[[Yu-Gi-Oh! Ultimate Masters: World Championship Tournament 2006]]'' does the following:<ref>{{Cite web|url=https://www.youtube.com/watch?v=K7Ff82erD3E|title=Yu-Gi-Oh! Ultimate Masters 2006 Glitch Compilation - Loops & More! (World Championship Tournament)|date=October 2, 2019|website=YouTube|publisher=Scrub Busta}}</ref>
* Both of the above "Cyber Blader" examples softlock the game. The monster equipped with "Snatch Steal" will display a never-ending animation of repeatedly changing sides, forcing the player to reset or turn off the game.
* In at least the two voluntary "Amplifier" examples, the game will automatically destroy "Imperial Order" or "Royal Decree" after several loops in order to end the loop.
* Interestingly, the infinite loop detection function appears to be built into (at least) the programming of "Royal Decree". For example, if a "Cyber Blader" loop occurs while "Royal Decree" is on the field, the game will destroy "Royal Decree" after several loops, even though it has no effect on the loop and the loop continues afterward as a softlock.
In ''[[Yu-Gi-Oh! Master Duel]]'', if an infinite loop occurs (even if it has a net change), the game will generally stop it automatically somewhere around the 10th loop for those consisting of activations,<ref>{{Cite web|url=https://www.youtube.com/watch?v=tSm3-gYl_jc|title=Will This INFINITE LOOP BREAK MASTER DUEL? {{!}} Yu-Gi-Oh! Ruling Twitch Highlight|date=February 15, 2022|website=YouTube|publisher=DistantCoder}}</ref> or the 16th step if it is caused by never-ending Continuous Effects. In the latter case, one of the cards involved in the loop will also be destroyed.<ref>{{Cite web|url=https://www.youtube.com/watch?v=AOoG3XyrnJg|title=This INFINITE LOOP BLEW MY MIND! {{!}} Yu-Gi-Oh!
