Pylos - Rules, History & Strategy Guide

Pylos was designed by David G. Royffe and published by the French wooden-game house Gigamic in 1986. It joined the celebrated Gigamic abstract line alongside Quarto, Quixo, and Quoridor — games built around a single elegant mechanic and crafted in beech and stained wood. Pylos became a fixture of European cafés and abstract strategy collections, picking up nominations and recognition through the late 1980s and 1990s as the wave of "designer abstracts" found a wider audience.

The game's lasting appeal is the tight tension between the 30 positions on the pyramid and the 15 spheres in each player's reserve — neither player can possibly fill the pyramid alone, which forces the central economic mechanic of the game: complete a 2×2 square of your own colour and take pieces back. Pylos remains in print today and is widely cited as one of the cleanest, most teachable abstract strategy games designed in the modern era.

Pylos is played on a four-level square pyramid: a 4×4 base, then 3×3, then 2×2, capped by a single apex sphere. Players alternate placing spheres of their own colour, building the pyramid upward — but the catch is that each player only has 15 spheres for a 30-position pyramid, so reclaiming pieces by making squares is essential.

1. On your turn, place one of your own spheres on any empty placeable position — anywhere on the 4×4 base, or onto a higher-level position whose four supporting spheres below are already filled.
2. If your placement completes a 2×2 square of your own colour (on any level), you may take back one or two of your own spheres from anywhere on the pyramid back into your reserve.
3. You may only take back spheres that aren't currently supporting another sphere above them. The take-back is optional — you can skip the claim if you prefer.
4. Continue alternating turns, building the pyramid up while watching your reserve carefully. Spheres taken back are returned to your reserve and can be played again.
5. The first player to place a sphere at the apex wins. If a player runs out of spheres in reserve and cannot move, they lose by default.

• Sphere economy is the whole game. Each take-back is worth nearly two placements — aggressively chase 2×2 squares of your own colour, and disrupt your opponent's 2×2 setups before they complete.
• Block opponent squares early. A single intruding sphere of your colour into a forming 2×2 denies your opponent a take-back, which is the most efficient defensive play in Pylos.
• Watch what you build for the opponent. Placing into a saddle that completes their support structure can hand them a free upper-level placement. Think one move ahead at the support layer below.
• The base is cheap; the upper levels are expensive. Try to use your "extra" spheres on the lower levels and save your reserve for level-2 and level-3 placements that put pressure on the apex.
• Keep mental track of which spheres are removable. A sphere that no one is supporting is a future free move — claim it the moment you complete a square nearby.

The standard Pylos rules used at most clubs and on Arcadia allow taking back one or two spheres per completed 2×2. Some house variants restrict take-backs to a single sphere per square, or allow take-backs only from the same level as the completed square. Tournament play uses the standard 1–2 take-back rule on any level. Larger 5-level "Pylos XL" variants exist with 25 spheres per side for longer, more strategic games, though the 4-level original remains the canonical version.
