FLIPS vs KEEPYBOO

A Brand-New Logic Puzzle: FLIPS FLIPS is a logic puzzle where you tap tiles in a number grid to switch their states and make the totals of every row and column match the target values. The rules are simple. Tap a tile to switch the number between two states: • Plus — adds the number to the total • Minus — subtracts the number from the total Match every total to the target shown to the right of each row and below each column to clear the puzzle. Which numbers should you add, and which should you subtract? The key is figuring out whether to flip each limited panel to + or −. ■ Recommended for Players Who: • Enjoy number puzzles such as Sudoku and Nonograms • Want a brain-teasing game for commuting or short breaks • Prefer thoughtful puzzles over games based on quick reflexes • Want a simple daily puzzle routine ■ 300 Main Stages Take on 300 puzzles that gradually increase in difficulty, from beginner-friendly 4×4 stages to challenging 6×6 stages.

Find the ghosts hiding on the board, using nothing but the numbers. Nothing is left to luck. All 2,000 puzzles solve by reasoning, start to finish. When you get stuck, a hint shows you why the next move is forced. ■ The rules A number in a cell counts the ghosts in the eight cells around it. A number at the edge of a row or column counts the ghosts in that line. Mark the cells you've ruled out with an ×. Reveal a cell with no ghost in it and you lose one of three lives. Lose all three and you start the puzzle over — on the spot, nothing else lost. That's everything. The first puzzle teaches you as you play it, so you can start without reading any of this. ■ If you love Sudoku, nonograms or logic grids KEEPYBOO never asks you to guess: the numbers always give you a logical next move. 2,000 puzzles, from gentle to expert, and the first one teaches you how. · One wrong tap doesn't end the board (three lives, as above) · Nothing is a coin flip. Every one of the 2,000 puzzles has been checked to solve by reasoning alone, all the way to the end · Rows and columns have totals too, so you can work the whole board ■ You don't have to be a maths person The 160 EASY puzzles are built entirely from moves where a single number tells you the answer. Higher sets add new kinds of move: comparing two numbers, then assuming a ghost is somewhere and finding the contradiction. The boards grow, but that isn't where the difficulty comes from. Every technique is written up in the Tips library, one at a time, illustrated on a real board. ■ Solve it, and a second puzzle opens Come back to a puzzle you solved by pure deduction and the ghosts now show faintly. The question is no longer where they are, but in what order to catch them. On the same board, the order can change the score several times over. Only the best order earns the diamond. Finish one with no hints and no mistakes and you earn a crown. Every one of the 2,000 puzzles can be solved, and then mastered. ■ 2,000 puzzles, ten sets EASY, NORMAL, HARD, EXPERT and MASTER — 1,110 puzzles — are free. Past those are EXTREME (690) and ULTIMATE (200), and the first several puzzles of each are free to try. A small board takes a few minutes; a large one takes as long as you like. Every puzzle is saved on its own, so you can go a little at a time. ■ At your own pace, for the long run No timer. Nothing that compares you with friends.
