Suguru vs Lights Out Infinity

Suguru, also known as Tectonics or Number Blocks, was invented in Japan. These puzzles have very simple instructions, but a very wide range of difficulties, from easy to insanely complex. Suguru is a great logic puzzle with two very simple rules. The cells in each puzzle grid are divided into groups, and each group contains the numbers from 1 to N, where N is the number of cells in the group. Thus, a group containing 5 cells will contain numbers from 1 to 5. The second rule is that no two adjacent cells, including diagonal, can contain the same number. Despite these two rules, some puzzles can be incredibly difficult to solve. Don’t be fooled by the size of the grid, and Suguru’s apparent simplicity. This is a puzzle that can, at its most difficult, challenge the most experienced of solvers. Be warned, this is an addictive puzzle like no other, and a uniquely satisfying one. In our application, we have created 6000 unique levels with varying degrees of difficulty. If you are playing Suguru for the first time, try the level “Novice”. Each difficulty level contains 1000 unique levels. Where level 1 is easiest and 1000 is the most difficult. If you can easily solve the 1000st level of one difficulty level, try the first level of the next level of difficulty.

Lights Out Infinity — a modern remake of the 1995 handheld classic, built for iOS. Tap a light and its four neighbours flip with it. Turn every light off. One rule to learn, three hundred puzzles to master. WHAT MAKES IT SPECIAL Every level carries a proven minimum. Not an estimate — a number checked by a solver that searched every valid solution, so matching it means you played that board perfectly. The hint always lies on an optimal path, and the stars measure how close you came. 300 HAND-BUILT LEVELS 150 classic and 150 hexagonal, from 5×5 grids up to 7×7, and from small hex boards to large. Symmetric patterns throughout — no random layouts. Up to 3 stars per level. HEXAGON MODE Six neighbours instead of four. The same rule produces strategies that simply do not exist in the square game, and no other Lights Out app has it. INFINITY MODE Pick a grid from 5×5 to 10×10 and a difficulty, look the board over before you start, and reroll until you like it. Every board is solvable, and its target move count is exact. DAILY CHALLENGE One puzzle a day, the same for every player worldwide. Track your run on a constellation calendar and compete on the Game Center leaderboard. 8 VISUAL THEMES Four free — Classic, Cosmic, Ocean and Monochrome. Four premium — Midnight, Aura, Amber and Moss. Monochrome is free on purpose: it is the most readable of the eight, and readability is not for sale. SMART HINT SYSTEM Stuck? The hint ring breathes over the cell to press, and it always sits on an optimal path. Three free hints per level. NEW TO LIGHTS OUT? A short tutorial teaches the rule inside a real board — three sentences, three moves, nothing to read through first. ACCESSIBILITY VoiceOver throughout. Every colour on every board measured against contrast thresholds. Full iPad layout. Seven languages, switchable inside the app. GAME CENTER 2 leaderboards and 16 achievements with custom artwork.
