Abstract Strategy

Abagio

User review: One player has twelve red frogs; the other player has twelve purple frogs. There is a yellow frog that can be moved by either player. The gameboard is a six-by-six grid. The perimeter squares are called the Outer Path. The Outer Path surrounds the squares called the Inner Path. The center four squares have been merged into the Pond, which is the goal area. Players roll both dice on their turn with the goal of getting one’s own frogs into the pond to win. The frogs may be stacked but an opponent whose frog rests on top of the stack can freeze a stack of two. An opponent can not freeze a stack of three. The stacking limit is five (except for the root and pond, which have none).

Stratego

From the box:

The gameboard is your battlefield. You have an army of men at your disposal and six bombs. Your mission--protect your flag and capture your opponent's flag.

Secretly place your men, bombs, and flag on the gameboard with these objectives in mind. But remember your opponent is doing the same thing, so you must plan a defense as well as an offense.

Once the armies are in place, advance your men. When you're one space away from an enemy, attack. You and your opponent declare ranks. The lower-ranking man is captured and out of play.

You control your pieces and risk your men in battles where the strength of your enemy is unknown. The suspense builds as your men move deeper into enemy territory. Move with caution and courage. The next piece you attack could be a bomb. And when attacked, it could "blast" your man off the board and out of play.

The first to capture an enemy flag is the winner!

This game is similar to, and almost certainly derived directly from, the H.P. Gibsons (UK) game L'Attaque (1909). It is not exactly the same, but not far from it (numbered pieces, spy (same name) can kill the strongest piece but only when attacking, flag, bombs, etc.) These game in turn almost certainly draw on the classic Chinese children's game Dou Shou Qi.

Different Edition Complications
When first produced in Europe, the most powerful pieces had higher numbers. I.e. the Marshall (most powerful piece) was a 10, the General was a 9, and so on. The higher the rank, the higher the number.
When they introduced Stratego in the USA, the numbering was reversed, so the Marshall was a 1, the General 2, and so on. The 1st rank (most powerful) was 1, the second most powerful was 2, 3rd most powerful was 3....
Then, in 2000s Hasbro re-imagined Stratego in the USA and made a few changes. They reduced the number of pieces per side (from 40 to 30), added additional powers, and changed the numbering to reflect the European system.
This caused extreme consternation with many faithful American Stratego fans who preferred the 'old way'. (Actually the second oldest way, but whatever.) Many of these insist on playing Stratego with the 'Marshall 1 system'.
This wouldn't be a problem, except any and all discussions of Stratego are fraught with misunderstandings by those who are unaware of dual numbering systems! Keep this in mind when reading information about Stratego.

Rumis

In the game Rumis, the players construct an Inca building with their stones. All players receive three-dimensional pieces made of wood, which they will try to position adjacent to their already placed pieces of their own color. All of their own pieces are of different shapes, which is a challenge to the three-dimensional imagination.

Cubic, wedge-shaped, or pyramidal volumes are different building limitations, which are imposed by the various building scenarios. Playing RUMIS, you will find that no game is similar to any previous one. Once your mind has mastered the puzzling shapes of the RUMIS pieces, you will explore the depth of tactical and strategic possibilities offered.

The rebrand by Educational Insights is labelled 1 to 4 players on the box, adding solitaire puzzles such as building a 3x3 cube with one color and building the various shapes using all the colors, following the rules of the multiplayer games while leaving no gaps in the structure.

Ingenious

Anyone who knows a little about Reiner Knizia’s games will know that the good Doctor loves games that deal with trying to get points in various different categories and then only score that category in which the player has the fewest.

The game is played on a hex board. 120 equally sized pieces, each consisting of two joined hexes, come with the game. There are symbols on each hex that make up the piece – some pieces have two identical symbols, some have two different symbols (not unlike dominoes). The goal of the game is, through clever placement, to obtain points in the different symbol colors. Points are claimed by placing a piece such that the symbols on it lie next to already-placed pieces with the same symbol.

The game ends when no more tiles can be placed onto the board or when a player reaches the maximum number in every color. Now each player looks to see how many points they scored in the colour they 'scored the least'. Whoever has the most points in their least-scored colour is the winner. Simple.

The author of the game has also come up with solitaire and team play, in which two teams of two play with each player not being able to see his partner’s tiles.

Pente

Pente is an abstract strategy game. Players place glass markers on intersections of a 19-by-19 grid (the same as in Go). The object of the game is to get five of your own markers in a row (4 with more than 2 players) or capture five pairs of your opponent's pieces. The first to do either wins. Capturing takes place when exactly two pieces are sandwiched between pieces of the opposite color. There are multiple variations of the game for greater challenge and complexity. The 20th anniversary edition is a deluxe version of the game with a large color game instruction book, quality game board, and six sets of different colored glass markers that allows play with up to 6 players.

Other five-in-a-row games include Go-Moku and Renju (which do not feature capturing), and Ninuki-Renju (which does).
