The locking links and a lock function can increase player engagement and can lead to increased play of the gaming machine. ## Claims ### Claim 1 An Electronic Gaming Machine (EGM) comprising: a first reel comprising a plurality of symbols, the plurality of symbols on the first reel comprising a first lock symbol; a second reel comprising a plurality of symbols, the plurality of symbols on the second reel comprising a second lock symbol; a third reel disposed between the first reel and the second reel, the third reel comprising a plurality of symbols, the plurality of symbols on the third reel comprising a symbol of interest; a processor coupled with and controlling rotation of the first reel, the second reel, and the third reel; and a memory communicatively coupled with and readable by the processor and storing therein a set of instructions which, when executed by the processor, causes the processor to: initiate rotation of the first reel, the second reel, and the third reel, wherein the first reel, the second reel, and the third reel each rotate independently for different amounts of time; detect, upon the rotation of the first reel stopping, a position of the first lock symbol on the first reel; detect, upon the rotation of the second reel stopping, a position of the second lock symbol on the second reel; detect, while the third reel is still rotating, a position of the symbol of interest on the third reel reaching a position through which a line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel passes; and in response to detecting the position of the symbol of interest reaching the position through which the line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel passes, stop rotation of the third reel. ### Claim 2 (depends on 1) The EGM of claim 1, wherein the line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel comprises a horizontal line between the first lock symbol and the second lock symbol. ### Claim 3 (depends on 1) The EGM of claim 1, wherein the line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel comprises a diagonal line between the first lock symbol and the second lock symbol. ### Claim 4 (depends on 1) The EGM of claim 1, wherein the line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel comprises a vertical line between the first lock symbol and the second lock symbol. ### Claim 5 (depends on 1) The EGM of claim 1, wherein the symbol of interest is predefined before initiating rotation of the first reel, the second reel, and the third reel. ### Claim 6 (depends on 1) The EGM of claim 1, wherein the instructions further cause the processor, prior to stopping rotation of the third reel, to determine a rate for applying a locking function and wherein stopping rotation of the third reel is performed in response to the rate exceeding a threshold value. ### Claim 7 (depends on 1) The EGM of claim 1, wherein the instructions further cause the processor, prior to stopping rotation of the third reel, to determine whether a locking function is enabled and wherein stopping rotation of the third reel is performed in response to the locking function being enabled for an electronic game. ### Claim 8 (depends on 7) The EGM of claim 7, wherein the locking function of the electronic game is enabled based on eligibility of the electronic game for enabling the locking function. ### Claim 9 (depends on 8) The EGM of claim 8, wherein the eligibility of the electronic game for enabling the locking function is based on a game play history of the electronic game for a current game session. ### Claim 10 A gaming system comprising: a processor; and a memory coupled with and readable by the processor and storing therein a set of instructions which, when executed by the processor, causes the processor to: operate a first feature of an electronic game, the first feature comprising a first indication of a lock function of the electronic game; operate a second feature of the electronic game independent of the first feature, the second feature comprising a second indication of the lock function of the electronic game; operate a third feature of the electronic game independent of the first feature and the second feature, wherein the first feature and the second feature are non-adjacent on the gaming system, wherein the third feature is disposed between the first feature and the second feature on the gaming system, and wherein the third feature comprises an indication of a symbol of interest in the electronic game; determine whether to apply the lock function of the electronic game; and in response to determining to apply the lock function of the electronic game: detect, upon operation of the first feature stopping, a position of the first indication of the locking function, detect, upon operation of the second feature stopping, a position of the second indication of the locking function, detect while the third feature is still operating, the symbol of interest at a position through which a line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel passes, and in response to detecting the symbol of interest at the position through which the line between the position of the first lock symbol on the first reel and the position of the second lock symbol on the second reel passes, stop operation of the third feature. ### Claim 11 (depends on 10) The gaming system of claim 10, wherein the first feature, second feature, and third feature each comprise a rotating reel of the gaming system. ### Claim 12 (depends on 11) The gaming system of claim 11, wherein determining whether to apply the lock function of the electronic game comprises determining a rate for applying the locking function of the electronic game and wherein the locking function is applied in response to the rate exceeding a threshold value. ### Claim 13 (depends on 11) The gaming system of claim 11, wherein determining whether to apply the lock function of the electronic game is based on eligibility of a player of the electronic game for the locking function.
