Slant is a clean, satisfying logic puzzle built around one simple idea: fill every square with a single diagonal stroke and never close a loop. HOW IT WORKS • Each square takes one stroke • Numbered dots sit on corners and tell you how many strokes touch that point • Every puzzle has exactly one solution — pure logic, no guessing • Close a loop and Slant highlights it instantly so you can undo and fix it SIX LEVELS TO MASTER Work your way from Easy (6×6) through Medium, Hard, Expert, Master, and Legend (16×16).

Verdict
The clearest difference is ads: Slant at none against Stack 101 Tower's shown. Stack 101 Tower's advantage is iOS requirement (12.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
