Tips & Strategy

Teaching SETI, first-game advice, strategy for income, techs, sectors and aliens, player counts and solo — advice only; the rulebook wins.

Advice, not rules: where anything here disagrees with the rulebook, the rulebook wins.

Teaching

• Start with the three boards and the round: five rounds, one main action per turn, free actions around it. Then walk the player board — every action and its cost is printed there.
• Teach by colour: probes (launch, move, orbit, land), then scanning and data, then cards and techs.
• Don’t explain the alien species up front. Say that three traces reveal a species, and read its sheet together when it happens. Peaky Boardgamer’s full teach follows this order.
• Show a solar system rotation and a sector being won before the first turn.

First game

• Expect the first game to be a learning game: the card combinations take a full play to click.
• Build income in rounds 1–2: tuck cards and take orbiters before chasing points.
• Plan probe flights for where planets will be after the next rotation.
• With Space Agencies, skip organizations in the first game, or use organizations 1–4 as the rulebook suggests.

Strategy

Early rounds

SpiderForge Games’ opening video aims for two or three income increases and a key tech in round 1 — launching, then orbiting Venus or Mars, is a common start. It favours credit and energy income over card income early, since you discard down to 4 cards each round.

Techs

The first probe tech (two probes) enables strong double-orbit openings; the asteroid tech turns every asteroid visit into publicity. Late in the game, the Mercury and launch-during-scan telescope techs make scans much stronger. Put a credit-giving computer tech in an early slot so data pays back soon.

Sectors and scanning

A bare scan with no telescope techs is weak in round 1. In 2-player games, think twice before a second marker in a sector you can’t win: the later marker wins ties, and it can set your opponent up. The SETI Fan Hub basic model discusses scan efficiency.

Aliens and gold tiles

Adapt when a species flips in round 2 or 3: with the Mascamites, for example, their landing cards and sample deliveries can replace the landing tech (SpiderForge Games’ alien guide). Reach 25, 50 and 70 early to claim the best values on the gold tiles before others.

Player counts

Three players is the most common favourite: sectors stay contested and downtime stays reasonable. Two players play fast but sectors fill more slowly (the neutral milestones help discover species). Four players compete hardest for planets and sectors but take longest.

Solo

Start at 1 star (no objectives), then move up. From 2 stars on, completing objectives each round matters as much as your own score: every objective you can’t spend feeds the rival. The publisher’s solo video walks through a rival turn.

Host game

Demonstrate passing before the first round. Give someone six cards and have them finish free actions, discard to four, rotate if first to pass, then choose their round card. Keep the next player taking turns: passing ends one player’s participation, not the whole round. Remind the table to finish free actions before resolving the pass steps; the rotation can change the position they had planned around.
