We solve Conway's Angel Problem by showing that the Angel of power 2 has a winning strategy. An old observation of Conway is that we may suppose without loss of generality that the Angel never jumps to a square where he could have already landed at a previous time. We turn this observation around and prove that we may suppose without loss of generality that the Devil never eats a square where the Angel could have already jumped. Then we give a simple winning strategy for the Angel.

A solution to the Angel Problem
The Angel Problem is solved, by describing a strategy that guarantees the win of an Angel of power 2 or greater, and it is shown that an Angel following this strategy will always spot a trap early enough to avoid it. Expand
The Angel Game in the Plane
• B. Bowditch
• Computer Science, Mathematics
• Combinatorics, Probability and Computing
• 2007
We show that in the game of angel and devil, played on the planar integer lattice, the angel of power 4 can evade the devil. This answers a question of Berlekamp, Conway and Guy. Independent proofsExpand
Sneaky Angel and Devil Game
• Mathematics
• 2021
In this paper we introduce an imperfect information variant of the Angel and Devil game, which was first introduced in 1982 by Berlekamp, Conway, and Guy. The Devil player has a winning strategy inExpand
An angel theorem for triangulations of the plane
Recently the so called angel problem was solved independently by four authors. We establish an analogous theorem for triangulations of the plane and derive a solution to the original angel problemExpand
Chain-making games in grid-like posets
• Mathematics
• 2011
We study the Maker-Breaker game on the hypergraph of chains of fixed size in a poset. In a product of chains, the maximum size of a chain that Maker can guarantee building is $k-\lfloor r/2\rfloor$,Expand
The Game of Cops and Robbers on Graphs
• Computer Science
• 2011
One of the main goals of the book is to bring together the key results in the field; as such, it presents structural, probabilistic, and algorithmic results on Cops and Robbers games. Expand
Chapter Ten – Games of Pure Skill and Competitive Computers
This chapter focuses on the evolution of games of pure skill that is devoid of probabilistic elements, including Tic-Tac-Toe, which dates back to about 3500 BC and Chomp, a Nim-type game, which postulates an M by N chocolate bar whose upper-left corner square is poisonous. Expand
Catching a fast robber on the grid
• Mathematics, Computer Science
• J. Comb. Theory, Ser. A
• 2017
It is proved that when the speed of the robber is a sufficiently large constant, the number of cops needed to catch the robber on an $n \times n$ grid is $\exp(\Omega(\log n / \log \log n))$. Expand
Problems in Ramsey theory, probabilistic combinatorics and extremal graph theory
In this dissertation, we treat several problems in Ramsey theory, probabilistic combinatorics and extremal graph theory. We begin with the Ramsey theoretic problem of finding exactly m-colouredExpand

Conway's Angel in three dimensions
It is shown that in the three-dimensional analog of the Angel-Devil game the 13-Angel can win and provides an explicit infinite escape strategy. Expand
The angel wins
The angel-devil game is played on an infinite two-dimensional chessboard''. The squares of the board are all white at the beginning. The players called angel and devil take turns in their steps.Expand
The Angel Problem
Can the Devil, who removes one square per move from an infinite chessboard, strand the Angel, who can jump up to 1000 squares per move? It seems unlikely, but the answer is unknown. Andreas Blass andExpand
Angel, Devil, and King
• Art, Computer Science

• 2005
This work considers Kings, who are Angels that can only walk, not jump, and introduces a general notion of speed for such modified pieces, which allows the Devil to encircle Kings of any speed below 2. Expand

This fascinating look at combinatorial games, that is, games not involving chance or hidden information, offers updates on standard games such as Go and Hex, plus analyses of the complexity of some games and puzzles and surveys on algorithmic game theory, on playing to lose, and on coping with cycles.
