Introduction

TN (short for Tuan Ngo) is a 3x3 speedsolving method proposed by Ngô Anh Tuấn in 2025. It is inspired by ZZ-CT and is a two-look LSLL method like ZB, divided into TNLS and TNLL.

Steps

1. Cross
2. F2L-1
3. TNLS
4. TNLL

TNLS (Tuan Ngo Last Slot)

TNLS solves the last slot edge and orients the last layer (except one last layer corner) by using VLS, OLL, or OLS-FE algorithms. Also, It is 100% possible to know in advance which subset of TNLL will appear from the TNLS step. TNLS requires performing a MCT (Mental Corner Twist) in certain cases before recognizing the appropriate VLS, OLL, or OLS-FE case and then executing the corresponding algorithm. The guide to MCT has been compiled by the author. It may be difficult to learn at first but with familiarity and practice, it is not a problem.

Subsets of TNLS

1. No LS edge in LL
   
2. LS edge oriented in LL
   
3. LS edge misoriented in LL
   

TNLL (Tuan Ngo Last Layer)

TNLL forces a last layer skip. The subsets of TNLL can be recognized by the corner in UBL or DFR, which can be known from the TNLS step. Also, recognizing the cases of each subset is exactly the same as two-sided PLL recognition.

Subsets of TNLL

1. TTLL
   
2. TTLL +
   
3. TTLL -
   
4. TPLL +
   
5. TPLL -
   

Techniques

Pseudo TNLS

Pseudo TNLS is an advanced technique in TN method. It forces a TNLL step from the third slot when last two slots have a corner is solved in one and an edge is solved in the other slot. Additionally, it is a combination of Pseudoslotting and TNLS, retaining the properties of them.

Subsets of Pseudo TNLS

1. LS edge oriented in LL
   
2. LS edge misoriented in LL
   

TNTS (Tuan Ngo Third Slot)

TNTS is an advanced technique in TN method, inspired by ZZ-C++. It forces a TNLL step from the third slot when last two slots have an edge is solved in one and either the OLS-FE or VLS F2L case in the other slot. Also, It is 100% possible to know in advance which subset of TNLL will appear from the TNTS. Additionally, TNTS requires performing a MCT (similar to TNLS), so mastering TNLS's MCT beforehand is essential.

Pseudo TNTS

Pseudo TNTS is an advanced technique in TN method. It forces a TNLL step from the third slot when last two slots have an edge is solved in one and the pseudo VLS F2L case in the other slot. Additionally, it is a combination of Pseudoslotting and TNTS, retaining the properties of them.
